Some Ninja 1000 and Z1000 owners have an issue with a dry clutch causing noise, chattering and inconsistent engagement. This mod was given as the answer but was never clearly detailed. Follow this 4 part log and you can do this as well. It has solved my chattering clutch issue. My 2011 Ninja 1000 with 10,000km would chatter and vibrate excessively when it was starting to get warm. It would do it sometimes when fully warm as well. I didn't modify the clutch rod, so far it seems fine without this part of the mod. Part 1 - Disassembly
