This is a tough one to explain. I have a 2000 426 with about 75 hours on it. I use Bel Ray EXL oil and change it every 6 hours. I have excessive clutch grab. I have never run across this before and was wondering if I should look into farther or not. What happens is this: No matter how slowly I let out the clutch and what ever throttle position I have it will grab and release and the bike surges forward and then it releases and surges ect.. Until I let it out enough to get the bike rolling. This happens in a very close range of releasing the clutch, I'm not trying to dump the clutch and stalling the bike. I did run a full synthetic oil for about 5 oil changes thinking the slippery synthetic would help, but I still had the same problems.
