I just checked my clutch after 50 hours of riding and found marks on the spring posts of my inner hub. The rest of the clutch is perfect (basket shows little wear and friction plates in spec.), but these notches appear to be from the springs moving around the posts. The bolts holding the pressure plate were properly torqued. Has anyone else seen their inner hub do this? I guess a $300.00 Hinson hub is in order. Thoughts?
