2018 280rr clutch feel

Featured Replies

Weird clutch issue I'm trying to solve on my rr. Lever is really light and the clutch feels lazy. If you rev it up and pop the clutch it doesn't slip, but doesn't give me the instant engament I'm used to. If I'm resting my finger on the lever and it gets pulled in the smallest amount the clutch disengages. I've replaced the clutch pack with a new one with no change. Today I installed the "hard" preload ring and the lever is still very light. Any advice is appreciated.

I did not measure the finger height, do you have the specs handy? I've owned the bike since early 2020, always used repsol oil. 

Yeah, we had the same bike for two years and the clutch was always perfect. Have you tried a rebuid kit on the master cylinder yet? The finger height can make it light or heavy pull. It sounds more like the m/c are sticking or slow. Have you used the wrong fluid in the m/c ?

I haven't touch the m/c, just checked to make sure it has fluid. I will take it apart tomorrow and measure the finger height.

Finally got the time to measure the finger heights. Not all equal, ranges from 13.95mm to 14.5mm. What are they supposed to be?
