I have been having some issues with my clutch dragging when cold. Even if I let the bike warm up for several minutes after starting it often stalls the engine when I put it into first. Needless to say this is not so great for the transmission either. I had it apart over the weekend and cleaned up the worn points where the friction and steel plates mesh with the basket and hub. This made a world of difference when it is warmed up but cold is still a problem. When I had the cover off and disengaged the clutch several of the plates stuck to the pressure plate and the others stayed put. Really looks like the stickiness of the cold oil is the culprit here, has anyone else had this problem? BTW, running Valvoline synthetic 20-50 motorcycle oil, was thinking about trying something else to see if it makes a difference.
