I had the clutch update done by my local bike shop and appear to have some issues. The first thing I noticed is that the engagement zone is much smaller now although it is still smooth. I can learn to live with that but I am also experiencing clutch slippage now. In top gear at 5K RPM (about 80 MPH) when I roll the throttle all the way open, the revs immediately go to 10K and sit there while the bike accelerates up to 125-130 MPH. It's hard to know if there is any slippage in first gear because the bike still pulls hard enough to wheelie but slippage is progressively worse as I go up through the gears. I talked to the service manager at the shop and he told me (believe it or not) that "it has a slipper clutch and it's supposed to slip." He next said my clutch was probably worn out and needed to be replaced. I believe the update included the center hub as well as new discs so I don't really believe that either. The bike has 7K miles on it and the clutch has never really been abused. I am running Amsoil 10W-40 synthetic (which this shop sold me) and he blamed that (snythetic oil) too. Any similar experiences or suggestions on how to proceed from here?
