I took my 02 gsxr 600 out today, and it would not shift right. It would only shift between first and second gears. When i pulled up hard it finally made it to third and fourth. But it would only go between two gears, either first and second or third and fourth, but never more than two. I have never dropped the bike or had any problems with it. It rode perfect the last time i rode it. any thoughts would be helpful.
