Just wanted to let everyone know that if you are, and you probably are, having coffee grinder noises accompanied with clutch grabbiness/chatter with a cold engine, drill the clutch basket. I did mine last night and you would not believe the difference. It actually feels like a working clutch again. I started it up earlier and took off after about 20 seconds and took off pretty hard and lo and behold it didn't try to jerk me off the bike. I would highly recommend this as a 1st mod to do on these bikes as it is a safety issue to me. There had been many times when I felt like I was close to losing control when taking off cold, especially trying to make a u-turn from a standstill. Plus this is a fairly easy mod; took me about an hour and a half from start to finish. Just figured I would provide some insight about this since there seems to be little documented about the success of this mod. Happy riding!
