Yeah, just put it all back together and start it. Listen for knocking/clacking noises. There may be other non-standard mods by hack mechanics. Due to cost of competing in MotoAM series, there's lots of family volunteer "mechanics" who may not know these bikes very well. Quite different from 1957 Chevy truck!
UPDATE


ran the engine in the garage for about 5 min, so not sure if thats warm enough etc. The smoke that PO said was present disappeared after a few mine. did a warm compression check and my gauge said 140psi for each cylinder.

not sure if that counts as a true warm test since I couldn't ride it at higher RPM or anything

Thoughts?
