@@dntlss You know, I really couldn't tell you for certain, but I'll try to make an educated guess here for you. I'd probably guess that assembly lube wasn't too common back in 1928, so using it today is kinda moot. I also believe that this particular engine gets its oil from a hand pump, so I don't know how important assembly lube is gonna be in preventing wear and tear when the engine itself doesn't have a constant circulating oil supply. You could lube the thing up, but it's probably not gonna stay lubed for long, and the oil that needs to get into oil passages and specific crevices might be blocked by gooey assembly lube. One other thing you might research was that in 1929 they introduced a throttle-controlled oil pump, which i have no context for, other than the names and an old article claiming that the throttle-controlled oil pump increased the oiling efficiency and overall health of the engine by a ton. So there ya go, hope my guesses might shine some light on the reasoning behind him not lubing it up like you would a 50s/60s/70s engine found in cars
@seanmakesthings

@@dntlss Read my other guesses first, but here's an alternate theory: he assembled the entire motor for clearance purposes, tore it down off camera, lubed everything perfectly and reassembled it for the final part of the video where he fires it up. Not really sure.

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.

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.

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.

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!
