At the race school I noticed my bike (Honda RC51) was abnormally jumpy off the line, so much so I couldn't really control my launch because it was so unpredictable when the clutch would engage. This problem is not nearly as present when the bike is cold, but just a couple laps and its very noticeable. I haven't actually torn the bike apart to see if the clutch is actually worn out, but I figure the bike has over 16,000 miles on it and therefore clutch must be the issue. So now that you know the history, can someone please answer the following: Is my choice of oil (10W40 Mobil 1 synthetic) causing the issue? If I decide to replace the clutch is it worth replacing all the plates and springs, or just the friction plates? Is there any affordable, complete, and recommend aftermarket clutch kits that would be better than OEM? I don't know of anything else to ask, but any reliable information is very much appreciated.
