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 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.
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.
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!
WOW !!!
Super sound ❤❤❤❤❤
Thank YOU!
Such a beautiful piece of motorsport history. it's so cool to see an old dog spit flames again!
First t time I have ever seen an engine assembled without prelude on pistons/ cylinders etc.
Great video..Thanks for no music and thanks for running the engine...Great job...

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.

Nice! Thanks for putting this together!
'tis a thing of beauty.
but the cam spindle mounting plate being secured by bolts from the inside gives me the yips.
Beautiful!
I just wanted to say thank you for the video on how to access the subharmonic register. Singing basso profundo is freaking fun.
That was really fun!
Great job. Very good video.
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.
Fantastic thanks for doing a video... do you have drawings for this engine by any chance?
This is amazing!!
Sick video
he is back les goooo
This video is the perfect asmr for men.
Missed you
Nice, now it only needs a cvk mikuni.
Beautiful engine.i wonder who was the genius who designed and b built the engine
Fabulous job, some very nice engineering in that engine.
Dude this is so out of left field for this channel haha! Love it!
Great video! Thank you.
Hey thanks for the video, it will help a lot when I get an F-Head.
wow its v twin engine Sir

1920's Harley 2 cam racing engines were stamped FH FHAC FHAD . Look up those.
so this is lies?

How Do you know if there is oil in a harley, its dripping under.. If not NO oil.😄
Where did you find those spark plugs?
i dont know whats worst the time to find original parts, or the time itll take to make to parts you couldn't find.
how much coffee did you have before the build😁
Como os caras que criaram a harley davidson eram criativos,
They were trying every type of valve layout and cylinder head.
How did you film this? The cam chest is on the wrong side, facing backwards as you're assembling it.
JH and JDH. Correct orientation. Go look at pics of a 1928 JDH Harley.
WHERE ARE THE GASKETS ???
Only 170g of oil, surly that's not enough!?
Rebuild every 5000 kilometers 🤣
I came across a 1929 Mercedes Benz in 2019. The owner wanted 10K. I ALMOST got it. Oh well.
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.
WHERE WERE U MAN, DONT ABANDON US AGAIN!!!!!!
XD
Not "less than", should be " fewer than".
So?😂
Looks fishy
