Loose ground on starter?
I think it might help my Like friends if I repeated my comment on "Re:Starting problems"
I wrote yesterday: if a starter fails to crank the engine or turns too slowly, the engine will not start.
Corroded or loose ground straps create a poor electrical connection and can create starting problems. Check the minus or ground wire bolt on the Like starter bolt, it has no lock washer or lock tight or anything to keep it from loosening up. It is also too short for its application. It should be replaced with a bolt 1/4" longer if at all possible. If that bolt comes loss your scooter will not start. It is only in by a few threads so be careful if you tighten it, you could strip it out of the soft aluminum.
