Haven't really worried about this, but ever since I bought my bike I can kick start my bike a few times and occasionally it will lock up to where it won't kick. I put it in gear, roll it back and forth, then it will free up to where I can kick it again. Any suggestions? I think it is a miss-aligned tooth on the kick starter gear but I don't know. Anybody else heard of this happening to their 08 450:excuseme: ?
