What parts and special tools will I need to change out clutch. Problem started with scarring on clutch basket. I just continued to ride it this way for a couple months now. It "bucks" real bad when starting in first and if I were to coast with the clutch in and give it gas it wants to go as if clutch wasn't engaged. What needs to be replaced....what would you do if it were your bike and you planned on racing it in 2 months, change it all?????? What does that include and what do I need ??? Obviously I've never worked on a clutch so I would greatly apreciate some help.... Thanks!
