I just bought a used 2002 Blaster bored out 50 I:I. I need some help on it over all i really dont know much about it so any one that can help it would be GREATLY appcetated. 1. the kick start is pushed back and is now gridding into the frame! i dont know what the deal is!:-/ 2. my next question is what all should i do for a good tune up on it to get it running top shape.
