Did a search but I only see the usual stuck clutches from a bike that's been sitting awhile. So I have an 04 R6, rebuilt the clutch with a Yoyodyne slipper. I've ridden it several days on the street with no problem to include a day of spirited canyon riding. I'm at a track and about the third or fourth lap the clutch pull goes extremely light and won't disengage the clutch. The bike still shifts fine between my quick shifter and slipper but I can't disengage the clutch. The cable is fine and it pulls the lever on the clutch hub no problem. It's just super light and doesn't disengage the clutch. I had the cover off and couldn't see anything wrong without pulling the plates themselves. Put the cover back on, with the bolt teeth aligned and no change. The oil is still new too from changing the clutch. Any ideas?
