Which fiber? That's exactly what happened to me, the very top fiber got really worn (no chunks but the blocks of fiber look hurt (slipped), and the steel under that looks like its been hot, it's black around the edges. Thats why I ordered a new kit. That happened to me when I road tested it after fitting it all up the very first time.I pulled my clutch back out again and found out one of the fibers is broken. I'll be ordering a new clutch today! It's gonna suck to be without a bike for awhile.
Coon mine was moving in gear with the clutch in when on the ground aswell, I'll attempt the adjustment process you posted up today, i was just going for 10-15mm at the tip of the clutch lever as per the manual. Thanks for the info I really appreciate it. I'll have another play with it today with the info that you've given me.
