I had an 04 gixxer 1000 and the clutch feel was excellent. no chatter at all. do you slip it alot and do you think that the steels are warped possibly??
The clutch does feel excellent except high rpm launches.
I have had the clutch out, filed the inner basket so it had no ridges, checked the steels no warpage, shuffled them around, scuffed the steels on the concrete checked the clutch right out no problems except the 3rd fibre in is wearing really fast.
I even tried drilling an extra 15 holes in the inner basket, and extra 3 in the outer basket for more oil flow and i put a small groove in the clutch push piece. the clutch is more oily now but still doing the exact same grabbing jerking on high rpm starts.
Im thinking of trying the k5 clutch fibre/wave washers in my k4 first.
i think im just going to have to bite the bullet and buy the brocks cushion kit.
