You had some questions about A-10 trannys, so here are the answers:
Oil, and level. Use engine oil, typ 40 or 50 weight, and fill until it starts coming out of the little level check hole to the rear of the kicker lever. There's a bolt or something you remove, and while the bike is level, just add oil through the pushrod adj access cover until it starts to run out.
Also, don't worry about the rollers in the clutch hub. a little grease on ass'y will do the job. They only do work while the clutch is disengaged, so the grease should work just fine.
Tried to use the link in the email to the pics, and it didn't work// Would like to see the bike, I'm always interested in creative ventures!
