Back in spring I ordered a stage 1 kit from RCR and I love it but I hear the belt rubbing on the cover a little bit when I let off the throttle after a wide open run. Rick sent me a black and white primary and a polaris purple secondary. Could the primary be to stiff or the secondary?

 

Could just be belt flex off of full throttle slapping cover. Try in neutral,gas it,let off see if belt slaps cover? Could be spring set up or a little belt stretch.

 

On the secondary i have it at the tightest setting. Ill give that a try because i am goin home tomarrow and going ridding this weekend.

 

i just reved up the motor in neutral and the belt did rub on the clutch cover, so it does rub in gear and in neutral.
