When letting out the clutch, as the bike starts to move, right as the real power happens, I'm feeling this little whoomp. What is that? Everything is running fine, just this annoying little thwump. Like its engaging MORE all of a sudden. I have about 24,000 on my Scrambler. I think it's always done this a little. I have a heavy duty clutch, which I have always felt had springs that were too tight. I remember when I had gold springs installed with the stock clutch, This was bad, and impossible to explain the "sticking" feeling the anyone. Then I changed to a EBC heavy duty clutch that worked great and solved that problem. I am wondering if it is getting old. How long should a clutch last normally? Is this something else?
