Coffee Grinder/ Clutch Chatter When Cold Fixed

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!

Yeah, can't remember seeing a solution to this problem... other than letting the bike warm up; interesting post, more details please.

Yeah that's exactly what I did. I pretty much watched the engine rebuild video by roach, I believe it is part 14, and followed what he did. His measurements and spacing are perfect.

That's very interesting, I may have to try that. I hate that grinding grab when I first get going.

It has solved mine 100%. Not even the slightest hint of grabbing anymore.

Can you get to this just via the clutch cover?

I just put my engine back in, and it is not coming back out. LOL.

As I understand it, the engine doesn't have to come out for a clutch job at all.
