Anyone every have issues with clutch slip under WOT? I replaced the OEM clutch because it was slipping bad when i got the bike back in FEB. They put a Barnett clutch, supposedly something carbon fiber and supposed to be an upgrade over the OEM.

Clutch feels ok unless i really twist it open, then it feels like it slips until the bike gets going up to speed. Otherwise riding around town casually it feels fine and even 50-75% throttle is ok.

Anyone ever had this happen? Barnett clutches any good? That's what the dealer installed. Is there any upgraded clutch kits out there for M90's?

09 M90 (250 tire on it, maybe too heavy?)
