Searching for a little troubleshooting help, please... I have 36K miles on my original clutch that has not been abused and has needed little to no adjustment during maintenance. Out of the blue, I'm now experiencing a "drift" in the clutch cable adjustment. I'll set it to the factory manual specs (1/8" free play at the clutch lever) and during the course of a ride it will change to much more free play (maybe 3/8" or so) and then return to normal by itself. No slippage, no grabbing...(maybe a slight amount of vibration that didn't used to be there, but it's hard to tell). Is this the beginnings of a clutch replacement coming due?? Why the changing free play? Heat related?? What's the normal service life of a clutch? All questions I have no answers to. I'm an aircraft mechanic so pretty knowledgeable, but have never had a clutch fail on any of my bikes. Yet. I appreciate all responses.
