Behold the Project Bike!
I wanted something not falling apart, that could be worked on/fixed/repaired and used, and this fit the bill perfectly: the engine actually runs, it definitely needs work but it's all stuff I can do, and it was cheap.
The engine is a single-cylinder overhead-cam four-stroke
No, I'm not missing that piece of case that's not there over the drive sprocket; it doesn't involve a seal or gasket, so not really worried about that; can always fabricate a piece to fit over and screw or weld it in place.
I got started on this before thinking "You know, I should take pictures and blog this!" Rundown as follows:
The gearshift lever was bent(common); a little time with a torch, vise, big crescent wrench and hammer reshaped it nicely. Yes, I took it off first.
It originally was street-legal, but most of the lights were gone. Since I want this for trails and such, I removed
the rear turn signal bases and bracket,
front turn signals(non-working),
headlight case(thing was covered with electrical tape, because what was still there was badly cracked),
and most of the wires for the above(more to go as I trace them out).
The battery was there, but dry and dead. It went, and the battery box, fairly sound but rusty. Without lights it'll run without the battery, so there went that weight.
See that yucky stuff on top of the crankcase? There was a little crack in the fuel line; that's been replaced.
Took the front wheel off to inspect the brakes; about half their life left, and working normally.
The rear brake was a different matter
The chain was in pretty good shape, once cleaned and lubed.
I mentioned that it runs, but didn't run very well. Big problem there was the air cleaner. On lots of bikes the air filter is a piece of foam that fits over a metal mesh support; you oil the foam, so the stuff the foam itself doesn't catch is trapped by the oil**. Thing is, it's supposed to be lightly oiled, not 'squeeze the foam and it drips' oiled. Cleaned the foam, cleaned the mesh(which was also oily as hell), let them dry and then lightly oiled the foam. Between that and fresh gas, it runs a lot better.
Big thing is going to be finding the cam chain parts, pulling the engine and replacing them. During which I'll also clean the carburetor thoroughly, and hope I can get everything back together correctly. Then, over time, clean and repaint the frame and tank, and whatever else needs doing.
We'll see how it goes.
*If you're not familiar with these, the inside end of the shaft is flat. The brake shoes fit on a pin at the bottom, and the top ends go on each side of the flat. Shaft rotates and forces them apart. Put just a dab of grease on the flats(making damn sure not to get any on the braking surfaces) and it'll help smooth things out.
**They make special oil just for the purpose; spray it on, let it soak in, and when the carrier evaporates it gets really sticky. You can use motor oil in a pinch, which is what I did for now.
