My clutch is stock Yamaha friction and metal plates. The problem that just started is it grabs really bad all of a sudden. In the past it has always been a little grabby when its cold, but now its grabbing really bad even when its warmed up. Its grabbing so bad its hard to get rolling in first gear. Is it just wearing out? Did I burn them? I did have a good clutching session on a vertical hill with a wet rocky section...if you know what I mean.
