I got frustrated and pulled the exhaust off, and the kickstand, and the footpeg, and the brake lever, and the clutch housing, to see how it worked. The only problem I have, is the only "resistance" I feel, is when it is turned all the way clockwise (to the point that it is trying to back the adjusting rod out of the inner nut-thingy....
Ah well, at any rate, adjusted it the best I could, and the chatter is still there, although it becomes totally quiet when I let the clutch out a titch and let it drag....
At least I'm sure the noise is coming from the clutch basket...
Wonder if anyone sells a new one?
