short & to the point here we go, picked up the bike from the shop took it for test run running perfect when i was coming to a stop i left the bike in like 3rd or 4th but never held in the clutch(stupid me) the bike was coming to a stop when the rpm's was too low it stalled out in gear.i guess you could call it that it locked up on me.Thats fine its normal that it does that,but when i went to start it up it sounded weird and didnt want to start.i thought it might be the timing got out of place or maybe something else dont know. so i checked the assy where the magnet,gears for the starter etc. go attached to the crank and it was loose. tightened up the bolt but nothing still. some of the parts look a bit worn and believe there is a bolt missing i need a diagram or online service manual to see what parts might be missing,but the question is could that be the problem or once i get this fixed i have to worry about why it wont start. if anybody could help that will be great.

 

Check for spark?

 

sounds like you need a new starter clutch or you sheared the key way on the flywheel.
