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!

ok check this out, this is the secondary sub-throttle. if I open the butterfly they will close when turn the key on, if they are already closed they make the noise like they cant figure out if they are closed or not, bad sensor?
