Hi, I have a whining too that stays whether the clutch is pulled in or not. I have checked the tensioner pulley bearings and they seem fine, so do the wheel bearings. The front pulley has no play that I can detect but there is a fraction of end float, no leaks or anything. I am thinking that something in the gearbox may be on the way out. The output shaft from the gearbox still turns at road speed whether the clutch is in or out so it would still whine, I just can't pinpoint it. Bike runs great although I think there is more vibration than normal.
