I just had a shop install a Ducati Corse anti Hopper clutch on my 999R Xerox and it is slipping. If i throttle it quickly and let off a couple times it tends to grab. I noticed the slippage when i was picking it up from the shop, they told me the plates needed to burn off a film. Now I have been messing around with clutchs on ducatis for a few years and never heard of that. The reason I had the shop install the clutch was because it came from Germany with no instructions, and no plates, so I thought the shop would know the right plates to put in and make sure there where no issues. Problem is the shop i deal with is 5 hours from me. Any suggestions beings it looks like I will be working on this? This clutch only has 4 springs. I thought that maybe if I went with heaver duty springs that it may help. The plates they put in are STM ducati plates.
