On my 2007 R1000, I replaced the clutch pack because it started slipping at high RPM. I got a factory kit, and made sure to be very careful to put the it all back in the order as stated in the service manual. When starting it up and for a split second I feel a little tug of the clutch engaging, but after that, it's not grabbing at all. I did soak the clutch pack in oil for about an hour. I can't figure out what could be the issue. Any help???
