I just bought my first 4-stroke...a 00 426. When taking off from a start it kind of jerks 2 or three times and surges to get going when releasing clutch . I have feathered it as much as I could thinking it was just me at first but it deffinatly does not feel right. Been riding all my life, is it just the nature of the beast or do I need to repair clutch? Also what or weare can I find valve clearance specs? You guys are the pros at this thumper stuff Im still learning! Thanks a lot!
