That old iron running gave me goosebumps. She sounds beautiful.

[@seanmakesthings]

So rad to see the old engineering of this motor like the screw in cam bushings/bearings in the case, what a trip. Thanks for showing us behind the scenes

[@pastorbobncc365]

Absolutely loved coming along for the build, have a blessed week my friend.

[@ronnieboucherthecrystalcraftsm]

side valve inlet and over head exhaust = wow that is some kind of exhaust valve assembly = 2 cams = thank you for assembly .

[@AS-bt4xp]

Housing covers, cylinders, flanges etc. have to be tight crosswise in any case, otherwise internal tensions and leaking follows! A good educated and teached mechanic has to know that!! Greetings from Germany!

[@rocker4144]

Such a beautiful piece of motorsport history. it's so cool to see an old dog spit flames again!

[@HarmonRAB-hp4nk]

dad sold my bike... I was named after a 1951 panhead... running all those years :-)

[@NitroModelsAndComics]

Seeing that thing light and then those flames. The tone is perfection.

[@scarecrow8004]

Ah the good old days when motors made a small enough amount of horsepower that you could drill holes in the connecting rods to reduce reciprocating weight. Absolutely fascinating. Loved the shaker twin video at the end, hold on tight or it'll be down the street by itself ... it craves to motivate.

[@FLORIDAMANIAM-he2lz]

Or you could just weigh and balance them

[@tnekkc]

My father had an old '74 when he was in high school in 1939, He was caught doing donuts in the parking lot, and had to eat his lunch in the office.

[@larsblankenfjell9814]

Best I seen for a very long time, really Love this engine!!!

[@davenorgrove3193]

Nice! Thanks for putting this together!

[@MonteFleming]

I just wanted to say thank you for the video on how to access the subharmonic register. Singing basso profundo is freaking fun.

[@evanreese4883]

Wow, the bass tones out of that thing! Sounds like a combination of fart bass and lip buzz. Now I just need to hear a beat over it.

[@user-ks5vm8ht7v]

WOW !!! Super sound ❤❤❤❤❤ Thank YOU!

[@Zulutime44]

What a beautiful exhaust sound. You know its a Harley.

[@psk5746]

Yeah because they all sound like shit

[@bmwtravel1100]

if you need parts for it, check with Reiman Harley Davidson in Kewanee, Illinois. Old Hank Reiman (not his son Roger) was an ace Harley tuner way way back.

[@MrStratbat]

Great video..Thanks for no music and thanks for running the engine...Great job...

[@FelipeMaldonado-wk4ne]

Great job. Very good video.

[@choppergirl]

You don't ever want it to stall out and quit, that will leave you stranded by the road. Maybe set your idle screw higher. Not about the sound, or even about the hp (well, if it was used for racing, then it is), it's about getting you there and back without issue or headaches.

[@redtobertshateshandles]

An old race tuner I worked with often the first thing he'd do was turn up the idle. And on a race two stroke turn it right off.

[@choppergirl]

@@redtobertshateshandles hard enough to keep an old engine running as it is. once you get it started you don't want it conking out on you all the time. it really swcks if your battery is dead, you have to kickstart or push start it again, or... your compression release is broken. I deal with all three all the time on the farm with this old junk.

[@johnarnold893]

@@choppergirl Battery, hah, what battery. It's a race engine and uses a mag for spark.

[@choppergirl]

@@johnarnold893 Fair enough, but a dead battery is huge concern on my bikes that are too heavy to push start and jump on. It will leave you stranded and phwcked. I can push start light cars on flat paved ground and jump in the seat and throw them into 2nd and start them (done that more times than I want to count), but pushing a heavy motorcycle to a running start and swinging a leg over and kicking it in gear without dropping it is beyond my stamina and skill level. Don't want no kickstart motorcycle ever again, you'll wear out your leg or break it trying to get that thing started.

[@jaynedoe1959]

That was really fun!

[@dlfabrications]

Why are you not adding assembly lubrication?🤔🤔 Did you grease or lubricate the lifters? How often would you lubricate up the lifters.

[@localenterprisebroadcastin5971]

Not to mention not torquing anything 😂

[@johnarnold893]

@@localenterprisebroadcastin5971 The torque wrench wasn't even patented until 1931 and it was years until they were being manufactured for general use.

[@localenterprisebroadcastin5971]

@@johnarnold893 The original torque wrench was invented by Conrad Bahr in 1918…swing and a miss bud

Impressive watching you assemble that entire motor using $14 worth of handtools. 👍

[@stevenleek1254]

Beautiful!

Beautiful!!

[@recoilrob324]

Look at those cam lobes!!! I've seen some asymmetry before but never such an extreme difference between intake and closing ramps. That's just crazy...but hey...it worked!!

Great video! Thank you.

[@TheRobyMann]

Sick video

[@YnEoS10]

Missed you

[@martykath4427]

It may have been initially built with cast iron pistons?? Those modern ones had large domes and ring tech that would be far more advanced than the original ones. I'd imagine this is a "manual squirter" oiling system as I didn't see an oil pump during assy. Haven't bikes come a long way from here.

[@Aleksandr_Naumov]

Very good!

[@kellywheatley807]

Nice job...

[@garypease7414]

Thats a first for me. I never new HD made a two stroke.

Holy f*** this is right up my ally 😂😂 I can actually restore one of these.😊😊

Sounds like a Hardly!

[@madaryakar9453]

i wonder why the making of this engine was stopped.! this was the king engine of the road

[@dogpaw775]

'tis a thing of beauty. but the cam spindle mounting plate being secured by bolts from the inside gives me the yips.

[@spiritofmilwaukee1927]

Hey thanks for the video, it will help a lot when I get an F-Head.

[@jbusta8548]

Cool beans what is the displacement for this engine?

[@jimevans9550]

Wow. They’re still the same, too.

[@jongirolami4978]

First t time I have ever seen an engine assembled without prelude on pistons/ cylinders etc.

[@bmwtravel1100]

yes, its odd, but two things: modern oil is light years ahead of 1920's technology, and the clearances on those old air-cooled engines was pretty was generous to start with. that said, yeah I woulda put a few drops here and there.

[@biggreasies537]

I owned one of those JDHs back in the 1970s, completely restored, sold it way to cheap to invest in equipment form machine shop. I see things on that engine that are not quite right.

Where abouts are you guys? I have a 1921J in bits that l need to make some decisions about.

[@TheIrishAmish]

Did you lap the case halves?

[@dlaws99]

Where did you find those spark plugs?

[@MountainGuerrilla]

that is a huge crank assembly, it must weigh 60lbs

[@JohnTaylor-gy2ps]

About the same level of technology as the latest model Harley Davidson's lol Check out the Vincent Black Shadow if you're looking for a V twin worth lots of money.

[@grantbuxton2108]

Wheels through time

[@Usnz411]

I think U should scan the motor with 3d or send it to special company to scan it for u cuz its very rear one

[@wiwingmargahayu6831]

wow its v twin engine Sir

[@marcellucassen8033]

Assembly lube or oil please, I didn't see it, it's important to use when putting an engine together.

[@Theogrn]

What kind of power will these engines make?

[@MAsWorld1]

I do love these but let’s be realistic: it is an IOE after all

[@spookydog6959]

how much coffee did you have before the build😁

[@SevenDays-3D]

первый раз вижу на двигателе мотоцикла МАХОВИК, почему сейчас не ставят не понятно ...

[@PanheadJeff58]

How did you film this? The cam chest is on the wrong side, facing backwards as you're assembling it.

[@hyperluminalreality1]

JH and JDH. Correct orientation. Go look at pics of a 1928 JDH Harley.

[@MichaelThomas-ps5qg]

Awesome stuff man 40k wow

[@nickyborrisino]

Rebuild every 5000 kilometers 🤣

[@h.nguyen4193]

i dont know whats worst the time to find original parts, or the time itll take to make to parts you couldn't find.

[@anthonypla7134]

Measures out oil to a fraction of a gram yet doesn't use a torque wrench. Cool engine though.

[@HarmonRAB-hp4nk]

looks like an old 45... dads was a 96 inch 1951 panhead bored. but the Norton commando was faster, cept being a thumper the piston stayed still and the bike went up and down LOL...

[@nigel900]

I don’t know… It seems if you’re going to go this far with such a rare and expensive engine… clean the rust out from between the cylinder head fins.

[@berkayy2455]

WHERE WERE U MAN, DONT ABANDON US AGAIN!!!!!!

[@hyperluminalreality1]

No sealer on the case halves? No assembly lube on moving parts? You don't like the big piston clips? Are those PEEK intake seals? The JH was NOT a factory racing engine and way more than 10 exist. It was the 61CI version of the famous JDH 74. Sold to the general public in dealerships.

[@hyperluminalreality1]

1920's Harley 2 cam racing engines were stamped FH FHAC FHAD . Look up those.

[@judod97]

so this is lies?

[@davidlarson3905]

1: there is sealer on the case halves. I always smear a very thin layer of black gasket sealant when assembling. Not sure if that made this film or not. Originally they had no sealer or gasket whatsoever 🤷‍♂️ 2: assembly lube is not necessary if you are planning on running an engine soon after rebuilding - which I did. 60 wt oil is quite thick at room temperature anyways. 3: no, I don’t like them at all (if you’re referring to the clips I used on these pistons) 😂 but they work great. More than one way to skin a cat as they say… 4: yes, those are PEEK seals. The brass originals can work great as well, but PEEK seems to be superior 5: I never said JH was a factory race engine - It’s not. But a 1928 JH is identical to an FH race engine in many technical aspects down to the bronze cam shafts. The only real differences (aside from the VIN number & casting numbers) between a JH and a direct action FH engine are the cam grind profiles, the lifter blocks, the combustion chamber shapes, and the flywheels. “Way more than 10 exist” is a stretch unless you know of a pile of them that no one else knows about. Quite a few have come out of the woodwork since this video was posted, but there seem to be less than 20 known still. Always looking for more!

[@fredrikgustafsson8]

How Do you know if there is oil in a harley, its dripping under.. If not NO oil.😄

[@GreenGrow-ck3pg]

​@davidlarson3905 how come few exist?

[@timgannon2993]

I don't think the words Harley and race should be in the same sentence 😂😂

[@windyworm]

Sorry guys, but the words “Harley” and “racing” really don’t go together if other engines are available. The Brough Superior would do 100mph straight from the factory.

[@mauricecanney7472]

Not "less than", should be " fewer than".

[@nopnop6259]

I don't know what about Hurly dabidsun it is but looking at this comment section and anything else to do with Hardly Functionson, it always attracts the biggest douchbags. Cool video nonetheless.
