History & Rebuild

Classic editorials were many through the 1980s covering John Harmon projects. Street Chopper magazine had printed various full page spreads on Harmon engines - above article by Bob Clark, images from Street Chopper Magazine 1981 - Hot Bike John Harmon archives  

Size does matter - above, John Harmon flat top 4-300" Venolia pistons were used for 3 years with no issues, below image of Harmon Arias pistons that came with Harmon kits.

Below, a new unused Harmon 120 cubic inch street kit. This one was sitting under a workshop bench in Sweden for over a decade untouched, It was one of two Harmon engines I had managed to purchase in Scandinavia.

Below, an early snap of the Harmon engine with the  top end disassembled. Every 12 months or so, the engine received new inlet valve lash caps, head/cylinder viton o-rings and a thorough inspection of internal engine wear and tear. The engine clocked up 1000's of kilometres every summer throughout Scandinavia without any major issues a part from the odd head o-ring letting go. The engine was a cold dragon to kick start for 5+ years until it was finally up-graded with an electric starter. The Harmon's top speed (using a 45 tooth rear sprocket) was clocked @270 kph. Around town, a 58 tooth sprocket was used in junction with an air shift as a teaser blowing off Jap bikes.

Owning two Harmon engines was a bonus. I've also done modifications and fix-it work on other Harmons. The below image was one of my own Harmon 120 engines during a second major rebuild in late 1999. The engine had ran well since its first rebuild in early 1994. As usual, like most Harmon engines, they require more attention and maintenance than other Big Twin engines. When they run - they run good, if slack haphazard short-cuts and cheap parts are avoided.

The first replacement engine part I hunted down in '93 was a Jims machine pinion shaft. Calling directly to Jim for a shaft was positive. He replied " Yeaps, no problem, I'm looking at a shelf full of Harmon shafts". The Harmon ended up using Jims pinion and crankpin, Jims lifter block assemblies, and up-graded Evo block assemblies. All Jims parts survived through the years with almost zero wear and tear - Thats Quality!

Largest Harmon 120 Engine - 183 Cubic Inches

The largest Harmon ever built and known, which I've personally seen that ran like a rocket was Jims custom 3 litre engine in Denmark. An original Harmon crankcase was used with one-off huge billet CNC machined cylinders and heads. The 3000cc engine displacement was also a kick start only. Image - Harley Davidson Magazine - Denmark. 
Below, a quick snap of a Harmon hardtail project by an old friend based in Belgium. His kick-arm lever should have been a taller version, but the bike was mounted with an electric start anyway - a wise move for this engine, unless one enjoys the classic art of kick starting with an odd kickback in the shin.

In The Beginning

Firstly I’d like to dedicate this page to the late John Harmon, and other bikers out there with Harmon projects. His brake away engine design was the beginning of a new era of big bore engine kits that went ballistic within the biker world after his passing. The John Harmon engine kits weren't flawless. There are several changes needed with the 120 design even before any assembly begins. The cylinder case stud holes were not CNC cantered aligned. Harmon cases have minor cylinder stud runout if replacing original cylinders. Harmon heads were finished without having steel inserts for head bolts. The addition of adding steel threaded inserts into the heads is recommended to keep heads from blowing head o-rings. The breather case oil hole also requires alignment trimming. The extended pinion shafts that came with engine kits should be replaced with a Jims pinion shaft. Crankcase bearing inserts on some kits are known to be slightly over machined. Early Harmon heads were designed for round top pistons. The early heads lacked power flow, and were remodelled with squish band curves and flat top pistons.       
A fastidious construction process is required when rebuilding these engines with several minor changes and modifications to make any Harmon Big Twin reliable.

Checking the pushrod fit on the Harmon 120 Shovel with retro-machined rocker-boxes (designed and made by Rick Hemi). A Vertex magneto and Carls Typhoon carbs were already being used on this engine before it's 2nd major rebuild. Creating and making your own design work is what makes any engine unique.

Harmon 120 Replacement - Cylinders & Pistons

John Harmon was way ahead of the pack using stronger V8 engine parts in his engine design. Original Harmon pistons are larger in diameter than 454 Chev V8 engines (4.250 versus 4.300). Piston pins are stock Chev V8 (.927). Added bore and stoke to make a 143 square displacement (4.500 x 4.500), or increasing the stroke (4.500 x 4.750 = 151 cubes) are possible options on Harmon engines.

The first parts that probably require replacing are the original Harmon pistons with other aftermarket brands machined finished with the same weight. Hyperformance pistons are recommended.
​Below, Hyperformance billet machined ductile cylinders are good recommended replacements when original Harmon jugs become worn out. New original Harmon cylinders are virtually impossible to find.

Image showing the size of Harmon pistons compared to stock Big Twin Shovelhead pistons

Replacing pistons is recommended due to the large cut-out on the original rear piston skirt. Quality made aftermarket suppliers like Hyperformance in the U.S. can reproduce billet CNC ductile iron cylinders and custom CNC machined pistons for John Harmon engines. Hyperformance front and rear pistons are the same weight by keeping a section of the cut-out at the original piston skirt length. This eradicates unbalanced issues, resulting in less vibration and pistons stable under thrust. Below, Hyperformance billet machined ductile cylinders are good recommended replacements when original Harmon jugs become worn out. New original Harmon cylinders are virtually impossible to find.

The best thing rebuilding Harmon engines are the amount of good quality machine shops who can supply all the necessary parts to get them up and running again. Replacement Harmon heads is like finding a needle in a haystack - so take good care them! One can have machine made replica heads if needed, but be prepared to pay a large cash stash - unless you know someone who can programme and use a high-tech CNC milling machine. Some street Harmon cases have enough material to extend bore diameters to 4.500. There is also just enough material on the heads, this would create a square engine @ 4.500 x 4.500 equating to 143 cubic inches.

Hyperformance cylinders, pistons and titan exhaust valves replaced the original Harmon parts. After the 2nd major overhaul, the engine ran well in Sweden and Denmark with positive results.

Original John Harmon cylinders will last for years with the advantage of getting approximately 7 rebores @ 0.10th increments. Those in need of replacement cylinders, hi-tech pistons, valves, and other quality made made products can source it all from one machine shop - Hyperformace USA 

Harmon Engine Parts - Cheap Short Cuts

If you're about to rebuild a Harmon engine, don't slap happy assemble the engine with cheap wing bling parts. Avoid any Chinese made engine parts, like bronze bushing and internal bearings. Chinese made bearings have a habit of falling to bits within a very short time period. Using US or European made quality engine parts that already have a history of reliability guarantees satisfaction if engines are assembled properly. I'm not here promoting one particular brand above other brand names. Most aftermarket parts I've used are from well known manufacturers that most bikers are already familiar with. The piston rod set above was pulled from a Harmon engine that had been micky mouse assembled. If the engine had been assembled together properly, it would probably still be running today. The engine required rebuilding because of shoddy workmanship.

Harmon 120 - Bottom End

A set of reputable aftermarket flywheels, rod and pins is essential to keep Harmon engines together. This engine on its 2nd rebuild received S&S flywheels, Carillo rods, Jims 3 hole crankpin, Jims pinion and sprocket shafts. The previous owner had built the engine with OEM shovel flywheels and rods which were shoddily put together causing engine failure. Some of the inner crankcase sprocket shaft bearings had disintegrated and disappeared somewhere. The left flywheel was also cracked, thus tilting the front rod which seized the piston rings with irreversible damage to the front piston and cylinder. The pistons were also running without any  piston pin bushings, and the engine had the wrong oil pump, including no oil filter. This is what usually happens to any engine when taking cheap short-cuts. Using good quality made parts makes any Harmon 120 engine run properly without issues. 

​Above, John Harmon's original crankcase GPRB (Grand Prix Racing Block) engine kit number 34.
At a certain RPM most Harley engines dish out rhythmic vibrations. Harmon engines are more brutal, they have a habit of slowly ripping and rattling bikes too pieces if parts aren't bolted down properly. I was once on the back of a hardtail Harman on a 300+ kilometre run. The owner had only one thing on his mind - full throttle without mercy! During the road trip, the Harmon snapped-off a mirror, and the rear belt pulley bolts became loose. Getting a numb arse is one thing, but the vibration on this Harmon rocket was severe. This was probably symptoms of an un-shimmed engine-tranny-frame. Swing arm or softail frames with Harmon engines are more merciful. Proper flywheel balancing is important on these engines, including a straight frame. The shimming of engine cases before boiling them down in frames will dramatically reduce vibration. Crankcases should be placed into frames to check if the engine mounts are even and parallel with no signs of wobble. Bolting engines down into frames - especially Harmon engines with even the smallest amount of gap between the frame and crankcase supports is asking for vibration trouble further down the road. This will add even more vibration through frames causing cracked fenders, broken mirrors, loose bolts, and missing parts. Harmon crankcases can also be slightly uneven on front or rear frame mounting casts. I've shimmed-up several hardtail frames, although in saying that, my own frame had to be shimmed. Transmission mounts are the same. Older frames, including aftermarket frames can have some serious uneven engine mountand transmission lugs. Avoid using salvaged frames from crashes and accidents unless a proper jig is used to check alignments. Bolting down engines and trannies by shimming run-out - if required, will lesson vibration considerably.

There's no escape - Harmon engines vibrate at certain RPM levels! External moving parts should be bolted down using locknuts with an added drop of blue loctite. This will reduce parts becoming loose or falling off on extended road trips. Whatever you do - Don't use yellow loctite, unless you're wanting a permanent bonded weld, and then gas-axing the bolt off later. I've seen this happen on main shaft sprocket nuts. Stainless hardware bolted into alloy threads should always use a dab of anti-seize paste to prevent galling. I've never had problems or issues over the years with bolts becoming loose on the Harmon. Parts were either bolted down with quality locknuts, a drop of blue loctite, or anti-seize paste. They say a smooth vibration is a happy vibration.

Keeping oil leaks from happening harmon engines is by using quality fittings, gaskets, seals and pushrod covers. Below, every workshop biker have their own favourite tools, a partial collection of Swiss and Japanese dial gauges used for various types of machine shop work. I personally avoid using Chinese wing bling made Junk stuff.

Harmon 120 - Crankcase Breather

Harmon breather cavities should be trimmed matched with the breather for maximum return oil flow from the crankcase. The breather hole can be square up easily with breathers. Removing the breather screen will also give less restricted flow. Any metal or other bottom end pieces entering through the crankcase vent hole will normally mean the engine has already blown to bits, so removing a screen is relatively safe. Replacing a machined billet scoop fitted inside breathers will ensure maximum oil flow. The only red-flag warning, is not to increase the length of the crankcase breather cavity dimensions beyond breather timing specs. Grinding and filing too much out can't be replaced. This job should be done when the crankcase is disassembled.

Below, the Harmon pinion shaft with an oil flow end-cap restricting oil flow to the crankpin. Without doing this - especially on these engines and most stroked engines, oil will over flow crankcases with too much oil. Quite a few Harmon engines including one new un-assembled kit I had sold had considerable amounts of oil spewing out of the breather vent.

Harmon Shovelhead - Inlet Valves

Original Harmon inlet valves are shortened Hemi 426 V8 2.250 inch valves. Replacement Manley valves can be purchased through V8 auto shops, or from reputable aftermarket Big Twin engine builders. The addition of lash caps are necessary on inlet valve-tips from pounding, and flattening the tip edge. For safety, lash caps should be replaced every year!

Harmon 120 Shovelhead - Camshafts

Harmon engines work best with cams having early high lift with long durations. I've tried various camshafts, with most of them working well from 3000 RPM up. Some to mention are the Andrews M & C grind, with the  Leineweber L5 being the best performer overall. The L5 has a .519 valve lift, the inlet valve opens @42 and closes @72 with a 294 duration. The Leineweber L51 cam is another goody. I was wondering why the previous owner was struggling kickstarting the Harmon when first viewing it. There was plenty of gas and spark, but do you think the engine would fire up. After an hour or so of kick starting, the Harmon finally breathed some life. When the cam cover was removed, I discovered the engine was running with the wrong cam, thus making it difficult to kick-start. The short length kick-arm was also a part of the problem. 
The above camshafts mentioned require correct valve spacing. Cam side play can be shimmed at minimum OEM tolerances. The Torrington needle roller should also be replaced when changing cams. Jims Evo blocks and solid lifters never gave issues clocking up road milage.

Harmon 120 Shovelhead - Oil System

Using good oil systems on Harmon engines will keep them running for years. Most quality brand oil pumps made in the USA will do the job. A larger oil tank with a capacity of 5 litres is recommended. Harmon engines should have an added crankcase vent line for crankcase breathing issues. Tapping a hole into the nose cone with a hose line to the oil tank is sufficient enough.

An added auxiliary oil pump was added on the Harmon to separately feed oil to the top end. The pump has functioned well with no issues from 1994 onwards. The heads were modified allowing oil to return externally back to the crankcase using -6 lines. This avoided the normal route of oil returning through the cylinders. Evo Sportster oil pump gears are used in the auxiliary pump. The pump is driven from a mini slot-hex extension that fits into the Magneto gear drive bolt head.

The most important instruments on a harmon are the RPM readout and oil pressure. A liquid filled PSI gauge and powerful oil warning lamp keeps everything in check - no matter what vibration the engine is dishing out. Many have blown engines to bits because of not having gauges operating where they can be seen.

Because of using two oil pumps and two Oberg screen filters, with the addition of four rocker boxes, plus external oil returns from the heads to the crankcase, Earls AN swivel fittings were used. With years usage of running this particular engine, not one fitting or line leaked a drop of oil, or blew a line. That's reliability one needs especially with Harmon engines. They can handle constant oil pressure feed in and out. The main engine oil filter and oil pump gauges ran consecutively @ 60+ PSI all day non-stop.

An integral part of any oil system is the oil filter. The majority of screw on filters require replacing after a few thousand kilometres on air cooled engines. The Oberg filter is one of the best performing aftermarket designs for any engine. The 600 micron screen stops everything right down to invisible dust particles. Changing oil using an Oberg filter is as easy as it gets. Undoing the four bolts will open one side of the filter, The screen can then be removed and cleaned, air blown and used again and again. The bonus of using Oberg filters is how fast it cools the oil down before returning to the tank.

Harley Engine Failure - Oil Change On Time!

Big Twin HD engines can take a hammering, but those thinking they're indestructible have either been dropping far too much acid or inhaling hi-octane weed. The endless amount of BT engines I've pulled down - like the Shovel shown below are usually the direct cause of irregular oil changes. Some owners I've known haven't bothered to change their engine oil and filters for years. Oil loses it viscosity much quicker in air cooled engines. The result of old oil running through engines ends up as pitch black sludge, which slowly clogs oil passages, and oil filters (if any) causing engines to run even hotter. This then destroys moving internal parts of their harden metal surfaces from sludge paste. Sludge oil mixed with metal pumping through engines will slowly destroy internal engine parts until something lets go - usually crankcase bearings or shafts. Oil well past its use by date will cause shaft pins and rollers to wear down quicker, thus destroying engines, exploding them to bits. Changing oil and oil filters regularly will ensure the lifespan of engines.

One of the best methods to change oil in HD engines, is first by removing the oil filter, draining the oil tank completely, and filling the oil tank with fresh oil. Start the engine, and then wait until signs of fresh oil runs out from the oil filter bypass mount. Once fresh oil appears, stop the engine, and then screw on a new filter. Restart the engine again and top up the oil tank.
Large engine displacements require larger oil tanks. You don't see V8 engines running with micro mini sumps, and they're water-cooled. Older generation Big twin engines over 100 cubic inches should have at least 4 litres of oil capacity. This allows oil volume to constantly flow through the engine and cool down before being recycled through the oil pump. I've never seen a Big twin engine blow to bits because of too much oil. For instance, the Harmon engine pinion, crankpin, sprocket shaft and crankcase roller bearings after 6 years of run-time were still within tight tolerances. Even the camshaft lobes, and lifters had no signs of wear, including the camshaft cone bushing and Torrington needle roller. The only parts replaced (at an earlier inspection during the first year) were the Crane rocker arm needle rollers. Galling was apparent on all four rocker shafts - which has nothing to do with oil, and were replaced, including a fresh set of bronze bushings. The needle rollers were the weak link not withstanding the rotation weight of the pushrods and valve springs. Inlet valve lash caps were also replaced every second year - a safety precaution for these particular engines. The Harmon oil tank was designed to take approximately 4.5 litres plus whatever oil is left through the lines, crankcase and filter. Neglecting oil changes on Big Twin engines can result in major repairs costing an arm and a leg that can be avoided -  Screaming won't help if your engine implodes because of neglect.

Have you checked lately where your one-time throw away oil filter is made? Cheap wing-bling imported oil filters can destroy air-cooled engines from clogging or failure from stuck internal bypass valves. Obreg Kits

John Harmon 120 Shovelhead - Modifications

One of many modifications were the replacement of the OEM Shovelhead rocker boxes. I had first begun by chopping up a pair of 1966 early Shovelhead rocker boxes that came off an engine from Baghdad. I had a constant flow of early and late Shovelhead engines, including Evo engines coming out of Iraq during and after the first invasion. The early and late Shovelhead engines were discarded for decades because of no apparent reason. Pulling down an early shovelhead engine that's never been touched since its assembly from the 1960s is a rear event. I even had one Evo engine from Iraq that had been found laying on its side inside a chicken pen with chicken shit all over it. The only thing wrong with the engine were the spark plugs and a botched homemade ignition module.

Chopping a pair of 1966 military cast OEM rocker boxes in half was the easy part, but cleaning them up to match together is another story. Crane roller rockers with Jims rocker shafts were used on this Harmon for many years. I found in the early stages while replacing Harman head o-rings, the Crane needle roller bearings had caused galling to the rocker shafts, and were removed and replaced with bronze bushings.

The first build was a mix and match of all sorts. The Harmon ran with Del-Orto carbs, Venolia pistons, Andrews cam, Vertex single fire magneto, tapperlite adjustable xxl pushrods, Jims solid lifters, triple valve springs, inlet valve lash caps, S&S oil pump etc. The Harmon was a kick start only. Through 6 years of kick-starting this monster, it had bent 5 kick starter shafts - it even bent a Jims machine shaft, which Jim himself couldn't believe, and wanted the shaft returned to see for himself with his own eyes. Kickback on this engine was quick and aggressive, it gave pain if the kick-arm had the chance to strike the lower leg. On various violent kickbacks, kick pedal replacements that had rubber chrome inserts would actually fly-off disintegrating into pieces. kick pedals from Chrome specialties, CCI & Zodiac all failed!

I ended up retiring the OEM chopped rocker-boxes and designed making my own. They were made from hi-grade billet alloy, with removable lids for easy inspection. This made it quick and easier when the inlet valve lash caps needed replacing. Larger diameter beefed-up rocker shafts were also made.

Using weak el-cheapo aftermarket wing-bling valve springs made in the "far east" on big cube engines is a no brainer! Top brands made in USA guarantees engine valve train reliability. Harmon engines use high lift cams requiring strong springs. Any of the above mentioned manufacturers make quality valve sets complete with retainers and keepers. Triple or double valve springs kits is optional. Harmon cam lift usually doesn't pass the .600 mark, so a strong set of double valve springs and titan retainers and keepers will do the job.           

Pushrods vary with one or two designs way ahead of the pack. Taperlite pushrods are probably one of the best designed constructed pushrods - if they're still available. Taperlites are made from chrome moly, the top ball ends fit snug, right up inside the rocker arm sockets. The lower adjusting ends have super fine threads, which completely removes all up and down play. Locking up the pushrod adjuster nut tight with a good nip ensures freedom from a rattling valve train. Harmon engines require the XXL set. This keeps more than half of the lower adjuster inside the pushrod. Sumax pushrod covers have plenty of inner clearance - they don't leak either when using their upper & lower silicon seals. Lower pushrod covers on both exhausts should be checked for clearance if using other brands. pushrod rubbing may occur.

The most difficult task completing the boxes were the underside centre locations and angles for pushrod covers to seal properly. A centring tool was made that fitted into the lifter blocks. The tool had a 12mm slide rod with a pin point tip that gave the accurate centring location. I'm still waiting for the return of this tool from someone who wanted to make a copy whom I trusted - He knows who he is!

Stock Shovehead lifters blocks were replaced with later model Evo blocks. The above image shows the severity of the front exhaust pushrod angle. Tapperlite adjustable pushrods with solid Jims lifters were used after the engine's first rebuild which clocked up over 5+ years of non-hassle running. There was also no cam or pushrod clatter, rocker-box noise or piston slap before the engine was pulled down for new modifications. The original Harmon head-cylinder viton o-ring seals were replaced with custom-made copper gaskets. These engines can actually run without head gaskets if heads and cylinders are perfectly machined matched. S&S one inch wide carb spigots were added as exhausts spigots instead of using the original one bolt exhaust hole. On the 2nd rebuild, the Del-Orto carbs and flanges were replaced with custom made spigots to mount Typhoon carbs. The original Harmon cylinders were replaced with Hyperformance jugs and pistons. The original cylinders were already at their maximum bore diameter @0.70 th., due the previous owner's sloppy engine short-cuts that caused the engine to internally destroy itself. This wasted 0.60 th of reboring to the original cylinders. A damaged piston with seized rings created deep scars down the front cylinder. This is what happens when bottom end assemblies are put together with mixed unmatched wing bling parts with sloppy tolerances. A set of 10mm compression release plugs were added, including titanium exhaust valves, a fresh set of 2-1/4" inch thin stem inlet valves and lash caps.

John Harmon 120 Big Twin Project - Stainless Hardware

Chrome Versus Stainless   

Hardware is an integral part of any Big Twin project, but what's the difference of choosing between chrome and stainless steel bolts, nuts and washers? If you live near or ride along coastlines, chrome hardware will eventually peel-off with rustic looking finishes - great for rat bikes. Quality grade Stainless hardware will keep on keeping-on! 12 Point grade 12 stainless bolts are normally used on tanks and other military vehicles. Knowing a direct US supplier will keep the costs down. The above image shows various sizes of 12 PT grade 12 polished hardware that was typically used on the Harmon project.

American made stainless Allen and hex bolt hardware is normally produced at grade 6 or 8. The quality isn't as good as grade 12, but it still beats imported Chinese chrome hardware that's normally available through aftermarket biker suppliers. Purchasing ready polished stainless hardware also isn't cheap, but saves the time and energy of manually polishing each bolt, nut and washer. I had my own 3 phase industrial polisher to to the job. My trusty old German 1961 FP1 Deckel miller, weiler lathe, and Swedish strand and arboga drill presses covered almost anything else. To stop galling, Anti-Seize paste must be used on stainless threads. If not, the next time any stainless bolt is removed, it will rip out the alloy thread it's attached too. The above image shows a treasure chest of US polished grade 6 and 8 backup hardware.

Counterbore tooling sets are a must have for certain custom made parts requiring clean flush finishes for Allen-head bolts and other work. I personally use Granlund counterbore tool sets from Sweden. Even though all sets are metric, the finished diameters are within US imperial tolerances.

John Harmon 120 Shovelhead - Drive-side

The John Harmon street Shovelhead drive side received a makeover from its former construction. I designed and made-up a newer heavy-duty adjustable plate that could hold everything in place. The two inch wide billet two section alloy plate is adjustable with a centre rod bolted to both half sections. It could easily adjust the drive belt up in a few seconds. Re-tightening the plate is with four 12 point bolts. The plate is used to hold the starter motor, the belt guard rail, the stone catcher, air shift pump, timing pointer, and left carb extension rod. Vibration issues on these engines can rattle items to bits, a solid thick plate keeps parts intact.

Getting oil out quickly from the heads is via external lines to the crankcase. The original Harmon cylinder oil drain holes were sealed and blocked when they were being used. Both front & rear external lines join together on the drive side beside the crankcase. This was one of the first engine modifications done in 1994. The engine had clocked up thousands of kilometres through the years with zero issues to all oil modifications.

Quality Workshop Tools - Don't Go For Less! 

Forget about using el-cheapo wing bling tools for engine building. Junky cheap tools made in China are what they are - Sloppy Junk! It's better to shop around for good quality brand name tools made in the USA or Europe. Even purchasing 2nd hand quality made tools will outlast and be more precise in tolerances than crap made in the far east. I don't blame China, I place the fault at greedy western companies cashing in for higher profit margins using cheap labour and low grade recycled steel.

Above, one of many workshops through the years using the same bench top design. Below, tools used to rip a part anything on the ground. Two top quality tool brands I personally recommend are Stahlwillie from Germany, and original Armstrong tools from the USA. I've had a few Snap-On tools that have snapped-off (made in China). Swedish Bahco screwdrivers are hard to beat, I've never had one fail me yet. Shopping for good used tooling can be normally found at industrial machinery dealers selling lathes, milling machines, and drill presses. The compressed images below don't show lifelike sizes of tools. For quick examples, in the top right image the blue coloured open ring spanner is 29mm, and a 3/4-2'' inch socket in the 2nd left image.

Street Harmon Shovel - Air Shift

In the early 90s, street air shifters weren't so common as they are today. Making air shift systems for Big Twins requires a mini air pump with enough air pressure to push the gearbox linkage arm super fast. A micro mini electronic switch valve unit is easily hidden out of sight under the frame. A homemade handlebar unit constructed from billet alloy is needed to hold a thumb push activation switch, a refill air valve, and a mini pneumatic gauge. The air line is connected directly opposite to the air refill valve using an air line push-in fitting. Air supply can be from any mini tank. The Harmon since mid-1994, had used a NOS slimline bottle mounted to the swing-arm drive side. There was plenty of air for several 1st-4th gear changes. Did it work? You can bet on it! Air lines have to be totally sealed and secured properly for the system to work. There were times at traffic lights when rice-burners got a shock of their life with the Harmon roaring up the street using air shift. Changing front and rear sprockets gearing the Harmon down gave quick power take-offs through the streets of Copenhagen.

The angle of the air pump to release, engage, and return to its neutral position is important. The air pump arm should be adjusted to move backward just past the engagement of gears. A much larger bronze bushing or needle roller can be used on the double arm lower support shaft. An STD 4 speed case with a full house of Andrews gears and shafts worked well with this engine. The less gears to change - the better. Below, the SSC Wiwo swing-arm had plenty of space on the chain side to mount a slimline NOS bottle for the air shift system. Two alloy machined ring mounts with stainless support lugs held the bottle in place without issues.

John Harmon 120 Shovelhead - Carburators

The Harmon engine's single carb per head is what make the this classic engine different to all other HD engines. The design had probably originated from the Vincent. The concept of using the same cast head for front and rear cylinders by just reversing the heads around was genius. Del-Orto and non-pump S&S carbs work well with the engine. The Carls Speed Shop Typhoon carbs also operate on this engine with minor adjustments. Zipper Thunderjets will also add a 3rd fuel circuit supply eliminating flat-spots on CV carbs.

For years, the Harmon engine had run with two 40mm Del-Orto carbs. It ran well, the carbs were easily accessible to fine tune or be removed from the engine within a few minutes. New parts for 40mm Del-Orto carbs are still available through various suppliers around the planet. The only minus for this particular model is the rubber mounting from the carb spigot to the head. A solid mount carb to head mount flange is superior for this engine due to vibration.

Carls Speed Shop Typhoon carbs were used on the 2nd rebuild. The engine response from these billet machined carbs was instant with no delays. I also used a Carls Typhoon carb on a 132 cubic inch Knuckshovster which also had an amazing fast full throttle response with zero lag-time.

Another 120 cubic inch Harmon Shovelhead engine kit I had owned, It was sold to a friend who decided to use 2 Qwiksilver carbs. The engine response was quick, but both carbs had horrible clattering sounds at idle. The carb slides would constantly rattle and could be easily heard a street block away. This engine was bolted into a hardtail frame. Within one year, the Harmon engine ended up vibrating almost everything that was bolted on the bike. Mirrors would snap off, bolts would come loose, and the vibration was extreme. The engine also left pools of oil wherever it was parked. The main cause was the pinion shaft not having a restricted end cap to stop excessive amounts of oil filling up the crankcase, which then ends up all over road pavements and footpaths from the breather vent. 

The Carl's typhoon carbs worked and operated extremely well on both engines with instant response time.

Using one Carls Speed Shop Typhoon carb on a bike is something, but having two of these cnc billet machined carbs running on one engine is insane. The John Harmon Shovelhead 120 ci engine had two Typhoon carbs  pumping out street gas with a blend of leaded aviation fuel. The mounting system was tricky, but anything's possible. Extra 12mm adjustable support rods were added underneath each carb. This kept the weight of both carbs from cracking the inlet spigots when vibration occurs - which happens on Harmon engines.

Above, a quick workshop snap during the rebuild, below the finished project using proper photo-gear. 

Harmon Flat Top Piston

Early Harmon engine kits were with round top pistons. The heads were without squish-bands. These engine kits were lacking in horsepower until the heads were re-designed in the early eighties. Anyone having early head designs are out of luck to replace early heads for later model heads - there are none! One can either machine make new billet heads identical to the later John Harmon heads keeping the 2 carb design, or use a set of blank STD heads using one carb. Images show an original late model flat-top Harmon piston.

If there was ever an image worth remembering - this is it. A snap shot of a Harmon piston within the first week of purchasing the 1st Harmon engine. Notice the monster inlet valve cut-out clearance, which is the same size as a stock Hemi 426 V8 ci valve. John Harmon was certainly well ahead of other aftermarket engine designers in the early 80's. The smaller piston is from a worn out mid 70s HD 1340 shovelhead. Below, a set of original Harmon 120 Arias pistons that had run with OEM 1200 shovelhead rods - a no brainer!

Harmon 120 Ignition - Vertex Magneto

All quality made ignition systems work on John Harmon engines. The Vertex, a single fire magneto has had an excellent reputation within the V8 world, grand prix, and used on nitro drag engines for decades. Vertex Big Twin models come with their own nose cone by Karata Enterprises USA. The Vertex is supplied with a high voltage transformer producing a constant flow of hot spark to the plugs. The more more revs, the more spark the magneto produces. A Vertex magneto was used on the Harmon engine since its first rebuild without any problems of malfunction. The Vertex mag is heavy and bulky for those who are weight conscious. The cam cone housing by Karata is well made designed made to last. Timing the Harmon engine with a Vertex magneto is straight forward - like any other engine. Once TDC has been established, the magneto needs to be turned approximately 10mm anti-clockwise with the points ready to open. Ignition setup can't get easier than that. The magnetos transformer produces more constant high energy spark than other ignition systems. This Harmon engine was more than responsive using a Vertex magneto.

The Vertex magneto gave unlimited amounts of voltage to the plugs via a transformer through the years with 100% reliability. Karata enterprises were the USA supplier for Vertex magnetos and back-up parts.
Below, workshop quick snap, Vertex magneto mounted to the Harmon 120 engine. The first rebuild included 0.50th Venolia pistons, S&S flywheels, carillon rods, Jims pins, Andrews high lift cam, black diamond exhaust valves, replacement inlet lash caps, crankcase bearings, shafts, Del- Orto carbs, tapperlite xxl pushrods, oil tight sumax pushrod covers, Crane roller rockers with bushings (not needle roller cages), jims non adjustable solid lifters, a set of 1966 OEM early shovelhead chopped rocker boxes off an engine from Iraq. The engine performed well using tight engine tolerances. No piston slap, zero valve train & top end noise. ​

Harmon Shovelhead - Scandinavia

The Harmon had done a run along the southern coast to Goteborg some years before with zero issues. The large ugly Danish number plate was removed for the above snap.

Harmon Shovelhead 120 Big Twin - DIY Custom Exhaust

Stock OEM HD frames require modification clearances for Harmon engine exhaust ports. It's easier to use aftermarket frames that have more front and rear tube space, rather than chopping-up and altering stock frames. Designing your own exhaust system on Harmon engines is straight forward with whatever finished concept one desires. Stainless tubing with 54mm diameter was used on this project. A supply of 90 and 45 degree bends made it simple creating the necessary angles. ​Extended spacers were welded to the head, I used modified S&S one inch inlet spacers. This gave the addition of using two 5/16 UNC bolts securing the pipes. Carbon slash cut ends with baffles kept highway patrol happy. I avoided leaving the engine idling more than needed. Both pipes after the head flanges would glow lava red.

Workshops - Scandinavia : NZ : Asia 

Having enough room to create a mess without having to worry about anyone screaming about the mess is always a bonus. DIY workshops have been many, mainly because of constantly moving or shifting off-shore. Some were poky little garages, while others had enough room to construct 10+ metre workshop benches.

Quality workshop tools are addictive! Those shifting house, on the move, or spending considerable time off-shore - like myself, can always place their workshop tooling securely in lock-up container storage. Accumulating good tools can take years. Selling workshop-gear can be done in a day, but there's no reason to sell-off workshop equipment - unless retiring. Think before you sell stuff, you may regret it further down the road.

John Harmon 120 Shovel - Kick-start Only

The kick-arm used on the Harmon was the tallest strongest solid model available on the market.

The Harmon had its off-days over the years, but when it was on the open road, it roared like a 70's Mack truck on steroids. At times, it was ridden and treated without mercy. The Harmon liked a quick twist of throttle through the gears all day non-stop. It didn't matter if it was snowing @ minus -5C or during the warm summer months - the engine ran! At night the red lava glow of the rear pipe scared the crap out biker friends. It was normal when idling for too long. The only part I ever regretted removing off the bike was the kick-starter. I used to enjoy watching others trying to kick start this "cold dragon" without warning them how painful it was to have the kick-arm pedal returning up faster than lightning bruising legs. Once, in the early years, the kick-arm pedal on the Harmon had actually hit my leg so hard, it shoved my leg up over the handlebars. I would normally kick start the engine with one knee bent up on the seat to get maximum height leverage. Below snap, the Harmon at a biker meet during the 3rd year of its 1st rebuild. 

Today, kick-starting engines is a bygone era with only those having nostalgia classics from the 1970s and before who are left. The art and technique of kick-starting Big Twins certainly varies from engine to engine. The Harmon, when cold, would normally give a series of violent kick-backs to begin with. The single fire Vertex magneto was one probable cause for kickbacks. The engine didn't like to much gas pumped down the spigots either. Removing the front spark plug, and turning the engine over a few times evaporating gasoline was ritualistic with this engine when flooded. A hot Harmon is a good Harmon, the engine would normally fire up on the first or second kick using no gas.

Two meter tall bikers with plenty of muscle power even struggled kick-starting this Harmon up - including a few patched gang members who suffered some serious kick arm bruises. Being only 70 Kilos, I used technique instead. I would kick the engine over until the front inlet valve shut on the compression stroke, and then give the engine an almighty whack - which worked most of the time.

The tallest offset kick-arm made it easier to start the Harmon up. Powerful kickbacks were common on the Harmon if the front inlet valve wasn't shut on the compression stroke. Other biker friends didn't bother to try again when they received brutal kick-backs from this engine. The kick arm assembly was removed and replaced with a low reduction starter after 6 years of kick-staring this cold dragon. Below, a second rebuild minus the kick arm.

John Harmon 120 Shovelhead - Rick Hemi

John Harmon's legacy still continues today even after 4 decades since his engine was first designed. Harmon engines hold their own special nostalgia because of its unique design. The 120 cube Shovelhead engines - even though the rarity of how many have survived through the decades are owned by biker enthusiasts around the planet. Data shows Harmon's are still blasting on highways through Scandinavia, Holland, France, UK, Japan, Australia, NZ and the USA. 

The John Harmon 120 Shovelhead engine is classified as an old timer these days, but you'll be hard scratched to find any plastic, or any cheap wing bling bolt-on parts on these engines. Most Harmon Shovelhead owners take pride keeping John Harmon engines for what they were designed for - A 1980s muscle engine.

John Harmon 120 Shovelhead - Rick Hemi

Most John Harmon Shovelhead engines through the decades have been modified in some form or another. Some have blown to bits, or have suffered engine failure due to maintenance issues. A few owners have even changed the engine design to run with one carb inside of two - Why? This beats the purpose of what the Harmon engine was known for, a two carb engine. One thing I can personally vouch for, a Harmon engine does run if quality parts are used, and if maintenance is kept up to scratch. The engine on this page clocked up thousands of kilometres from 1994 onwards. The quick spec above lists some of the virus parts that have been used since it's first rebuild. All engine parts were either made in USA, Europe, or by myself, nothing Chinese!

John Harmon 120 Shovelhead - Achievements

Back in the mid 90s, I didn't know the difference between a knucklehead to an Evo, or had ever owned or built any American V2 iron, only lots of different V8's. My 1st big twin was an early shovel, something I regretted buying a month later because it lacked power and was shoddy rebuilt with wing bling junk. It was imported from the States in 92. The 67 shovel had been used in the 1991 Stone Cold movie, ridden by actor Robert Winley who starred as "Mudfish" (deceased 2001). The bike was completely stripped down - engine and all, and modified and rebuilt. In the end, it was probably the best decision to dismantle and reconstruct the bike as a new project.There's no better learning curve than pulling something apart yourself and rebuilding it from scratch. 

Classic American iron, go slow engines, go fast engines. In 1990, David Campos held the world speed record using two Shovelhead engines for 16 years with a recorded top speed of 322 MPH (519 KPH).

The above Harmon engine had easily reached 275 kph at 3/4 open throttle and would have probably reached the 300 mark on full throttle. It wasn't a lightweight bike. Blue 242 loctite kept hardware intact. Vibration on this engine rolled in around 3000 rpm and dropped off at 3500 rpm. The shimming of the engine, and tranny to the frame kept the vibration level at a minimal. The engine performed well using tuned supertrapps or with straight pipes. There was zero valve train noise, and no piston slap like on other Harmon engines due to sloppy tolerances. The engine ran on single grade SAE 50 HD oil, and was automatically replaced after 3000 km of run time no matter how good the oil still looked. Oil is cheaper to replace than worn out overheated engine parts. Oil pressure remained constant at idled and high rpm. The engine through the years never dropped or leaked oil. The only hassle was when kick starting this beast, if the engine became flooded. Kickbacks by this engine were brutal. The removal and drying of the front spark plug, and few rotations of the engine was required. The Harmon would normally then fire up on the first kick with no gas. Compression release plugs were added after a few years. An electric starter was added after years of kick starting.

Hardtail Harmon 120 Shovelhead

One of two John Harmon Shovelhead engines I had owned - It liked being thrashed and ran like a hot rocket.​

Those who haven't kick started super Big Twins like these Harmon 120 engines probably steer clear of them using electric start instead. All I can say, I've had my fare share of Harmon kick backs over the course of many years. Nothing beats the adrenaline rush firing up these classic engines manually. 

Wrinkle Finish - Respraying HD Engines

Masking and respraying engines is certainly an art in itself. Over the decades, I've seen some real shoddy resprays because of the lack of not putting some real effort to complete engine paint-jobs with a clean finish, and without peeling off in a matter of months. For instance, the Harmon engine only received one VHT black matt can spray job that lasted for 6 years without flaking. The cylinders and heads were thoroughly cleaned, and sprayed over a few days with several coats. The heads and cylinders were slowly baked in an oven for an hour or two which hardened the paint.

Wrinkle finish resprays are easier to apply, but the trick to have an even finished look is by applying even light coats using VHT. Spraying heavy coats will cause the paint to run and sag. Spraying wrinkle paint on engine parts outside in sunlight also helps the drying process. A finished light coat should be sprayed when the previous coat has nearly dried. This will give an even wrinkle effect almost immediately in front of your eyes. Rotating the parts around in direct sunlight will ensure a 100% even wrinkle finish.

Above, a plain Jane showing the finished result. It gives engines a clean spotless cosmetic finish. Fresh coated wrinkle finish paint jobs should be untouched for at least a week, with engine parts placed and rotated in direct sunlight during this period. This allows the paint to harden properly before grinding head and cylinder fins. Baking wrinkle finish parts in ovens can be done, but the slow method of drying parts in direct sunlight for 5-7 days is recommended first.

Grinding fins is a pain in the arse, but needs to be done to finish any resprayed engine. The cylinders should already be rebored or honed before spraying and grinding work begins. A small hand held variable belt sander is required, including a stack of replacement sand bands. Staring off with 40/60 grit, this will clean off wrinkle paint from fin edges. After cleaning off paint from fin edges, the art of moving the sander evenly around cylinder and head fins is with 100 grit. Placing each part inside a half-ripped up cardboard box helps angle and stability while grinding away. Shaping the width and getting even bends on fins is done on the final stages. Heads should be placed on cylinders to check that they have the same matching curves and widths. It's important to thoroughly wash down parts in kerosene, or other cleansing liquid, and air blowing until all alloy specks and grit sand is removed.

An S&S 113 Evo engine that had blown apart received a full rebuild with a wrinkle finish makeover. The following items are required to paint engines properly. Super sharp razor to fine trim masking tape along edges, quality grade masking tape, a hand-held variable belt sander, VHT wrinkle, matt or gloss heat resistant paint, sunlight, an oven for gloss and matt spray jobs, and most of all - some patience.

This old classic S&S 113 was in a shoddy state. A set of new valves, roller rockers with bronze bushings, lifters, pistons and rings, re-bored cylinders, crankpin, case bearings, camshaft case bearing, cone bushing, replacement oil pump, rebuilt carb, and a cosmetic wrinkle finish and hand done fin grind gave some fresh life to this engine.

Quality Versus El Cheapo 

I've avoided Chinese made wing bling junk all my life. I'd sooner pay more for any product or part made in the USA, Europe and other Western countries. Many of those classic Big Twin parts catalogs like, V Twin, Chrome Specialties, and Custom Chrome were always filled with cheap junk manufactured from the far east.
The blame is directly placed on those profiteering from their own designs using cheap Chinese labor, and then marking up retail prices earning substantial profit. Maybe that cheap crankpin, piston and cylinder set from China were produced by Tibetan or Ughur slave labor.

Carb powered engine rebuilds. Non fuel injected V2 engines are best. Carburetor engines are simple to repair when carb issues occur, which is relativity rare, but happens, usually caused from subpar engine building and poor maintenance i.e. fuel bowel adjustment, needle adjustment, gasket o-ring intake air leakage etc.      

Working on the 132 megabore engine. Andrews high lift cams, Proflow oil pump, S&S crankcase, Hyperformance ductile cylinders and pistons, Jims solid lifters, Orberg oil filter, 5 liter stainless oil tank.   

Above, all American Euro made parts right down to the last bolt guarantees satisfaction with long term reliability. Using cheap wing bling made junk manufactured in the far East should be avoided, even if it's parts for lawn mowers.

Anyone remember those fancy mat finished colored PM 6 piston race brake calipers from the '90s? The 132 rigid ran with two of these brake stoppers. It seems this model is now discontinued.     

Because I lived in Scandinavia for some years, it was more logical to purchase European made parts for Harley projects. Below, an Erickson 120 straight spoke rim from Sweden bolted to an 8"inch over 6 degree rake fork from SJP. All engine and tranny parts are sourced from the USA. The only issue having so many spokes is when they need to be cleaned. 

Like workshop tools, quality made Big Twin parts from reputable aftermarket suppliers will outlast anything produced from the far east. If engine parts don't have small print where they were originally made, it's guaranteed a wing bling product from some Chinese factory using recycled car wreck metal and cheap labor. The quickest way to destroy an engine is by using low grade engine parts. For example, using cheap camshaft cage needle rollers instead of Torrington cage rollers can suddenly collapse, and grind down the cam damaging the camshaft lobes, the lifter rollers, and cycle specs of metal through the entire engine wearing out surface harden moving parts beyond repair. Below quick snap, one of the lowest softail project Big Twin rigs I've owned.

Building big twin custom bikes can take up to 1000 hours from start to finish. It's all about how much work is involved. There's no escape ordering parts from various suppliers offshore. Normally, frames come from the US and EU, engines and running gear from the US. Most other accessories like gas tanks, forks, lighting, electrics, fenders, and forward controls are sourced from reputable suppliers. Everything else is custom made.       

Ridged hardtails will always be the iconic symbol of all custom big twins.

The more cubes the better! I built this rig in Scandinavia as a second bike with top American and European parts. 

Above, this classic XL Ironhead received a few modifications to get it running as a city hack runabout. Was it worth it? At the time it was, but as most already know, these XL engines have limited top end power compared to big twins.

Why use 40 spokes? This 160 rear spoke rim made the 132 hardtail more classy giving it the nostalgia look of yesteryear.     

By 2030 images like this will be banned off the internet. Gasoline is already a dirty word, so enjoy running around on anything that requires fossil fuel. Riding gasoline MCs will become nothing more than a past pipe dream. The squeeze is already here, the parrot propaganda machine from all sides of the globalist hierarchy want us to have nothing, own nothing and be happy about it.

Custom Harley paint jobs through the 90s were mostly done by Kent Customs in Sweden. Below, a sample of his marble finished artwork on a rigid hardtail project.   

Below, Atlas Coyote hardtail frame, custom made five litre stainless oil tank, 6" Racor-Orberg oil filter, and the 132 c.i. S&S mega bore case. Cylinders & pistons are from Hyperformance with Jims Machine and S&S bottom end. Not the best garage point & shoot snap, but then it's better than nothing.

Building this rig took around 500 hours of slow labor, endless smoko breaks, and countless cartons of Scandinavian ale. After run in, this 132 cubic inch hardtail ran and sounded like a rocket on steroids. The engine like the Harmon, had compression release plugs to ease starting. The Carls Speed Shop Typhoon carb functioned extremely well on this engine. The 132 never missed a beat, never leaked a drop of oil, and had zero valve train and piston noise. The 5 liter oil tank, oil cooler, and Oberg screen filter took care of lucubration. This 132 engine design is still the only one of its kind world wide - Now that's something. 

My first Big twin was an early shovelhead. It leaked oil, and ran like a worn out flathead. Oil leaks were coming from everywhere, especially from the primary, rocker boxes, pushrod covers, oil fittings, and the tranny. These two builds shown above and below were the total opposite. They never leaked a drop even with double the amount of lines and fittings.

I was called a nutter, insane and crazy by friends when I had first told them I was considering to construct a megabore 132 cubic inch 4 cam engine into a hardtail frame. Most were riding softails, and wouldn't even think riding rigid bikes. The comfort, and smoothness of twincams is hard to beat. Hardtails on the other hand are for old school freaks - like myself, and used to kick starting 120 c.i. Harmon engines for years. Was it worth building the 132? You Betcha, and I'd build another rigid with even a larger displacement at the drop of a hat. A 160 c.i. panshovster sounds good, who knows, let's see what the future holds past 2024 if cheap gasoline still exists. Maybe moving to Venezuela is an option, I've traveled through Venezuela twice on different journeys throughout the country with no issues. One thing Venezuela isn't short of, is dirt cheap 97 octane gasoline, and American cars and pickups.      

Once Upon A Time - Down Under 1970's

During the late '70s I was a V8 rev-head Down Under before I began my solo overland travel adventures around the planet. It was a time when there was plenty of work, good pay, prosperity and total freedom. It was a time without internet, wifi, smart phones (hell phones), narcissistic selfies, and online trolls. The cries and screams of wanting Socialism within the western world was still under the rug - except Sweden, that has now become a failed Socialist program. In the '70s, if one wanted to debate on any particular subject with others - you'd do it face-to-face without spitting or triggering on each other, and walk away in a non-hostile atmosphere. Universities back then had just begun their campaign agendas to dumb their students down as we see the outcome today of so many useful woke idiots. An off-spring of generations of totally dumbed down indoctrinated people with fried brain syndrome with induced delusional psychosis. Today universities no longer provide knowledge, they destroy knowledge.
I'm fortunate, I didn't go to university, my brain and self-critical thinking is still intact.

In Aussie during the '70s, classic American cars, Aussie assembled V8's and Harleys were cheap and plentiful. Gasoline was nine cents a litre, the weekends were free, the beaches packed out, and the sound and roar of V8s, hot rods and Harleys were heard up and down streets. Rent was cheap, food was cheap, employment was plentiful, and Aussie beer tasted great (VB, XXXX & Coopers) 
​During the mid 1970's, I had owned 3 classic V8's at one time, a '69 Javelin coupe. I had transplanted a 340 W2 Mopar V8 SB under the hood. The engine used to scream from Brisbane to Cairns and back again without blinking an eyelid. The gas price back then wasn't even something worth debating about. I used a '59 Ford Fairlane sedan as a daily city runabout. It was purchased for 400 bucks off the side walk at the traffic lights. A 57 Ford Mainline V8 was another project, it was purchased from an old timer for 500 bucks, also from the pavement. It ended up with a BB engine. 

Many I meet ask why do so many Americans hate America? Why do Americans hate themselves for who they are? Who and and what caused the dumbing down of Americans?

Where did the root cause originate from….

In Moscow, in the 1920’s, the KGB had special schools training professors to infiltrate into Western European colleges & universities. They trained college professors specifically with techniques and abilities of structured social engineering and brainwashing, which manipulated their students minds to auto convert to communism and Marxism. American prisoners of war in north Korea had also received indoctrinated communist brainwashing. 

They then began the set up process, by infiltrating into the West  by setting up their first group think headquarters at the Frankfurt School of Germany through the 1920’s. They were given the boot out of Germany in 1933.

It was here where the first Group Think Critical Race Theory was born.

The majority of Frankfurt school communist college professors became best selling authors. They moved implanting themselves to other locations throughout Europe, and eventually arrived in to the USA and taught in the finest universities.

Their goal was to ignite a Communist Marxist Socialist program, by creating a cultural revolution, with change of language, art, film, theology, etc.
These college professors became intellectual celebrities – they were all agents of the Frankfurt School.

When Hitler rose to power in the early 1930’s, the Frankfurt School of Marxist professors packed up and fled to America, where ‘mysteriously’ by some invisible force were hand picked, and given top positions of the highest academic honor. They became tenured professors in the most prestigious schools and universities across America.

What’s happening in the USA in 2022, is the exact repeat of the Communist Marxist Revolution that enslaved Russia, creating it into a totalitarian controlled state. Any nation divided from within will eventually collapse and fail its economy as seen through recorded history.

The Frankfurt School Communist playbook principle formula uses psychological warfare to stir the envy, to arouse the jealousy, to promote anger of those within populations who feel disaffected – To Hate Their Country, to rebel in woke minority groups against each other i.e. the race card, anti religious backlash. Many are woke triggered and fueled with indoctrinated delusional psychosis and they don't even know it.

Instead of facing reality, the delusional person would rather live in their world of make-believe. But in order to keep faking reality, they’ll have to make sure that everyone else around them also pretends to live in their imaginary world.
In simpler words, the delusional person rejects reality. And in this rejection of reality, others have to play along with how they view the world, otherwise, their world will not make sense to them. It’s why the delusional person will get angry when they face someone who doesn’t conform to their world view.

I bought the above 4x4 Nissan double cab for a slow towing runabout. The double cab shell had been placed on an early Nissan Patrol chassis with an added one meter extension. The front inner and outer fenders and bonnet were extended six inches to accommodate a larger radiator to cool the 5.7 V8. The rear tray was from a Nissan king cab. As usual, I couldn't help myself adding a few light modifications to an already heavy modified vehicle. The engine got a Mallory electronic ignition, high output alternator, K&N carb filter and dust cover, headers and twin exhaust, 33" Serengeti rubber on 15" inch black 12 slot rims, slimline custom made alloy running boards, rear 4" custom made roll bar, and an industrial mat sprayed paint job. The V8 never missed a beat. The rear diff was massive, it looked like it came from a truck. I was fortunate enough to find 2 rusted out wrecks of the same model Patrol on a farmers property. For a carton of beer, I took both front and rear crown wheel and pinions, axles, and transfer cases.     

The only panel replacement required was another king cab tray. These were already like hens teeth, almost impossible to find, but I did manage to get a clean non rusted non dented tray. The small block Chev V8 ran well on cheap LPG, almost half the cost of 91 octane gasoline.  

The rear G60 diff housing built like a truck with solid large diameter axles.   

Frankfurt professors were trained to reprogram students minds regarding the history of their nation, their culture and race, history of religion, history of the world – their historical foundations of life by subjected mind control thought.

Just go on Social Media, the Internet, turn on TV, what is being taught at schools up to PHD level – everything today is nothing but social engineering indoctrination.

Freedom in America is in total free fall. Canada, Australia and NZ are close behind. Europe is already done and dusted.

Students are taught and brainwashed to view their societies, their life through the lens of communist indoctrinated Socialism and Marxism.

The majority of the global middle class today have no clue having zero knowledge of history or factual data. People have been deliberately dumbed down to the point of no return. People have become social media junkies. Believe me, there's more to life than wasting it away on social media platforms.

Classic biker workshop snaps are only here because I worked in a few of them during the 90's. Notice the Shovelhead engines sitting on pallets. They were trade ins, no one wanted them, you couldn't even give them away. I built the Evo hardtail for a customer taking 200 hours. Projects like this were in demand during the 90's. Bikers wanted affordable custom rigs with stock engines. I had good contacts in Milwaukee drop shipping plain Jane Evo engines, primary gear and 5 speed trannies for 3k. Below, servicing a Twincam at another biker shop.    

For those having high regard to Socialist/Marxist/Communist values - Just try living in Cuba, Nicaragua, Bolivia, China or in Venezuela as an average peasant, and see how that works out for you. Probably not long, maybe a month? maybe not. Experience all those Socialist promises that were actually "made up lies" by using deceptive tactics. This certainly doesn't hurt Socialist regimes ruling over their populations by any means necessary.
​
Modern society today is fully controlled and manipulated by puppet Globalists, MSM, social media platforms and Goolag. Within a short time period from now even silent free thinking will become outlawed.
Overthrowing western values and capitalism has been in the works for decades - what a plan yes? A global controlled Socialist/Marxist system (UN Agenda 2030) with promises of free benefits for everyone living under a slave controlled system full of snitches snitching on one another. What happened to Venezuela is a dire warning to all western nations - Hello, wake up out of dream state! ​

During the seventies in New Zealand, used American V8s were plentiful. Every man and his dog had one. '57 Ford Customlines could be bought for under 400 bucks, and Ranch-wagons were giveaways. When I was sixteen, my first passenger road trip though the South Island was in a '56 Ford V8. From the Bluff to Picton, the 272 V8 never missed a beat. Hitching lifts as a teenager through the 1970s was common practice.        

Socialism has in-fact a 100% failure rate. Excellence is achieved by productive competition and internal manufacturing. When competition is removed, the population relies on Government to be the dictator of your mind. They end up controlling and manipulating people's minds to their full advantage. Historical facts don't lie. Under Socialism, social justice disappears - freedom of speech disappears, critical thinking vanishes, the right to bear arms disappears, including freedom of religion - all down the toilet.
​Marxist Socialism leads directly to hardcore Communism - It never delivers what it promises ...the latest terminology "Democratic Socialism" uses the exact promises as other drained Socialist Marxist countries have used through history. Its glossy sugarcoated to dumb people down! Are you dumbed down? Maybe you don't even know you're being dumbed down listening, and believing "useful idiots" on the Socialist bandwagon? It's all about control and power.
​There is no such thing as free benefit handouts - The cash has to be extracted from somewhere. Employed working populations end-up paying through high rip-off taxation - How's your gasoline tax? cigarette and alcohol tax? income and import tax? One look at the Scandinavian tax system shows where the cash is being squeezed out from. I was paying 55% tax from my monthly salary in Denmark. 25% tax on anything bought, and employers preferred hiring those who had a mountain of debt. Scandinavia is used as a Socialist model, but in fact they're not! They all work on capitalist values. 
​Be a good slave now, and work your bone piece off! Don't complain, just be a good citizen and shut up.
​Decriminalizing cannabis sounds great, another agenda ploy dumbing down youth populations. Most who have stoned brains don't even know what's happening around them, let alone what day it is. Smoke that weed man, and collect your free monthly benefit handout without worrying who's paying for it! Like in ancient days, Rome used sport to pacify their population, nothing new here under the sun. Netflix will finish you off sucking out the last bits of your brain replacing it with a liberal mindset - Got It?

A 1972 HQ One Tonner. It was parked up in a farmers barn in the middle of nowhere for some years. The Ute originally came with a straight 6 engine. Sometime during its life a cast-iron Chev 5.7  V8 was bolted into it. The one tonner was used  as a hack runabout. It got a pull down, chassis sand blast, and sold as an unfinished project with a full Statesman Caprice front and spare mint cabin.  One Tonner history   

Just think how rapidly Western countries have self-dissolved within a mere four decades. No matter with how much new technology we own and use. Global control over all land, all property and populations has always been the agenda. Those believing in the Climate Change narrative really need to do a self-reality fact check.

Honestly, the western gimme gimme spoilt entitle Gen Z generation is the most dumbest generation of all human history. They wouldn't have a clue how to dig holes planting trees, hand milk cows, plant vege crops, built fences, hunt for food, or survive on next to nothing. The Gen Z are an embarrassment to mankind. Wokeness brainwashing has replaced all self-critical thinking. The above judgement is based on hundreds of Gen Z'ers I've met with all the same results - Brain damage. Who is to blame? Parents, the indoctrinated educational system, legal pharmaceutical depression drugs, social media addiction, group think, 24/7 fake MSM news.

Above and below images, the land of plenty 1986, when V8's were a dime a dozen and high grade gasoline was 19 cents a liter. This classic Ford XA GT 351 V8 received an engine overhaul, and was resprayed on the front lawn in Bellevue Hill, Sydney.

Older V8's weren't so complicated. All they required was a healthy set of points, condenser and cap, non-leaky leads, a set of new spark plugs and coil, a non-leaky carb, and a reliable starter motor. That's it. Filling up with gasoline and cruising down highways enjoying the sound and rhythm of  V8's is pure bliss. Those days are over, the globalist cabal want all of us to ride on mules and donkeys instead.     

An FJ45 1982 landcruiser 4WD I had rebuilt. It ran with a hot cast iron 5.7 Chef V8 with beefed up high/low transfer gears, 35" inch all terrains, double pumper 4 barrel carb, electronic ignition and tuned extractors. This classic flat deck got a new lease of life. It ran and handled the way it looked.

The small block Chev gobbled up the same amount of gasoline as some big block engines I've had in the past. The engine had zero issues with overheating, valve train noise and oil leaks.  

Anyone can make, create and design stuff if they focus their minds to do it. Nothing is impossible. It starts by a mere thought, a vision, a design concept scribbled on paper turning into reality happens if one pursues it. The most important of all, is to finish whatever was started. People who normally give up half through any project no matter what it is, usually never finish or complete anything through their entire life. It's all about the finished product, the expertise of something created personally by your own hands. It can be automotive, property development, landscaping, design furniture, leather work, including the artistic side like photography, drawing and sketching. Through the decades, I've personally learnt to follow my own instincts -  not others. If someone says to me "hey that can't be done, it's impossible", I will do it no matter how long it takes to prove a point it can be done. An example is designing a gasoline engine to run on 90% water. All one requires, is to build a multi rod cell chamber, a very powerful alternator, an LPG carb base plate, one way check valves, and stainless head and valves. Cell chamber rods must be as close to each other as possible. Rods require cleaning from time to time. Heating water extracting hydrogen gas is nothing new. Those out there with some intellect no doubt can easily figure the rest of the design to fully operate. Whatever you do, don't go down the path fiddling with acetylene and water - Its volatile! 

Below, those classic don't care grainy subpar roll film snaps have more value to look at them now, like this vertex magneto bolted on an Evo 1340. The engine received the usual modifications i.e. cam and carb change, Jims lifters and rockers, taperlite pushrods, breather, oil pump high speed gears etc. 

Never Judge People By The Way They Look - Big Mistake!

Not so long ago while in New Zealand, I was looking for a vehicle to travel through the country. While in Wellington, I had done the usual walkabout through used car lots scattered in and around Basin Reserve. An Audi A4 coupe caught my eye. The paint job and fancy wheels made it stand out from the rest with the asking price tag reasonable. I slowly strolled around inspecting the vehicle looking for defects, like scratched paintwork, ripped seats and worn cosmetics. There were none, so I was interested.
​There were two salesmen sitting at the back of the car yard outside their office enjoying some sun. They saw me, but never got off their butts to assist or help. At the same time, a Pakeha (white kiwi) strolled in and was casually looking at another vehicle at the same lot. He was well dressed carrying a briefcase. The fast response and assistance by the two car yard owners was impressive. They were eager to sell, they even gave the dude a business card before he vanished down the pavement. As for me, I was invisible, they weren't interested at all giving me the same treatment. Maybe it was my long hair, the tattoos, the colorful Colombian mochila and buff hoodie that put them off, or maybe it was because they classified me as a Maori daydreaming tyre kicker?
A few days later, I purchased this brand new RCZ, all paid for with no occurring debt payments. The car dealership Armstrongs was a street block away from the previous car lot where the Audi was. I decided to pay a quick drive-by visit before leaving the city. When I drove up onto the car lot, the Audi was still there. The same two guys were sitting in deck chairs at the rear of their car yard. When they saw the RCZ stop, they got up and approached it as though they had a guaranteed sale. When I got out of the car, they recognized me by the way I looked and by my apparel. With a grin, I said "You guys remember me from a few days ago looking at that Audi yes?" they both nodded heads, I then said "Both of you rushed to the dude wearing a suit and tie carrying a briefcase, and totally ignored me even though I was there before him, I was really interested to purchase that Audi - Big Mistake - Big Mistake" "You see this RCZ, I just paid cash for it, have a nice day" ​As the saying goes, never judge someone by the way they look, especially complete strangers - Got It?               

The Gasoline Days Are Over! 

Tick Tock ... 9 years till Agenda 2030 fully kicks in - You will own nothing and be happy about it.

Anyone remember the CD days? Each of these engines above sounded great at full volume. I had purchased the CDs back in '96 when high octane gasoline was still cheap and plentiful. In real time, I rebuilt countless amounts of these engines for customers. It was an era that most of us thought would never end. Thinking about it, If I could stick one of these engines up a Globalist elite's rear end sideways - I would do it.

Those who are still out there clinging on to the good old days of cheap gasoline, cheap oil, and endless supply of automotive parts are blind to the fact this won't exist by 2030. Most of you while riding your MC's, V8's and hot rods ignored all the warning signs 20 years ago. The globalist reset was already in motion with a global agenda to eradicate gasoline fueled vehicles, middle class businesses, all cash transactions, and to reestablish their own initiatives whether liked or not. Your own government has probably already been under control by WEF young global leaders i.e. Ardern, Trudeau, Marcon etc, who were placed there for one reason, and one reason only - To destroy their nations freedom and prosperity to usher in the skeleton frame of the NWO aka build back better using climate change as the scapegoat.  

The push for electric vehicles is now in top gear. The globalists and their useful idiots around the planet would prefer to have all of us riding push bikes rather than filling up gasoline powered transport. There's nothing better than smelling the fumes of 97 octane while filling the tank of a Big Twin or V8. Gasoline by 2025 will become unaffordable. It's the end of pump gas petroleum as we see it, unless one is lucky enough to be living in Venezuela. Instead, the crazy planet will bow to China, who will export millions of EV batteries filled with ingredients from the northern regions of Afghanistan. It's as though the world is hypnotized by saving the planet from fossil fuel production, but then re-polluting the planet with used toxic batteries. Mining for future precious metals certainly won't be achieved using EV machinery - Got It?

I was fortunate enough to have been born in the right decade. Since the 70's, I've owned, built and driven countless V8s, Big Twins and 4WD's while residing in different locations around the planet. It's 2021, take some good advice, sell off all those gasoline vehicles that aren't being used, get rid of all debt burden, and downsize to an affordable lifestyle. Things are going to get tough, real tough, so don't delay - do it today!

My own V Twins loved running on high octane gasoline. I even dropped a portion of 120 leaded avgas in the odd tank refill to clean the valves. Both engines ran like hot rockets, sounded like helicopters on steroids and guzzled gasoline like the tap turned on. The day gasoline becomes banned and controlled rationed becomes the end of all freedoms as we knew it. Enjoy riding those gasoline rigs while you can, time is running short. By 2030, gasoline will be erased for public use if the Globalists get there way.

The great leftist socialist global experiment is in full swing. SARS-CoV-2 mRNA jabs has created global populations into live lab rats. Brainwashing indoctrination is at all time highs. Doctors have become yellow cowards, while MSM pollute the internet parroting the same lying jargon. Gasoline has now become a dirty word, the gasoline days are over, enjoy using it while you can. Maybe when the increase of more sea and land volcanic eruptions begin pouring massive amounts of sulfur fumes through the atmosphere at unprecedented levels, the wearing of masks will then make sense.

Above, the days of medium format roll film. No, this isn't a negative digital image, it's only an enlargement taken from a proof sheet. It was normal to have negative medium format roll film images placed together on proof sheets before choosing whatever images were worth enlarging with original negatives. I used a Mamiya 7 for some years, and honestly regretted selling it. The classic Shovelhead above got a full rebuild, including an aftermarket S&S crankcase.         

An old timer dedicated to WLC flathead Big Twins taken with a rangefinder.  Below, mid 1990's hand held closeup snap using a Mamiya RB 67 medium format camera with a 90mm f/3.5 lens @ f/3.5 

Below, I still find the odd snap tucked away in albums and inside old hard drives. This one popped up in Aug 2021 while looking for classic overland travel images from the '80s and '90s. It would have been much better if I had the original negatives, but those were safely packed in deep storage in New Zealand decades ago.

Have you built, designed or made anything in your life, or are you just a typical keyboard warrior? Have you accomplished any long term solo overland travel journeys through continents? Have you bought and renovated run down properties and resold them? Can you hunt, cook and survive on your own or do you rely on the corner store? Do you live in debt up to your neck just to keep up with the Jones? Have you ever experienced what it's like to have all your freedoms taken away from you? By 2027 most who cannot think for themselves, who rely on government will eventually become desperate in one way or another bowing to their puppet globalist masters. The grey area of freedom we've all been accustomed to is vanishing into thin air as I write this. By 2030, the globalist will control all your freedoms, all your thoughts and treat everyone under their control as slaves.
