Automatic atv revving high? I got a 01 yamaha kodiak 400 4x4. Got it for a steal non running when I got it. It will not reach to speed. Clutch is good no slip and goes up hill in 4wd no problem. Just don't go up to speed. Cleaned out the primary clutch and it was full of junk that was blocking the plate from expanding. Got it to go a little faster but not as much. The clutch expands but seems to get stuck at a point and not go any further. Looks like there's some bad groves in the cam plate but not as much as the housing where the weights sit. Should I be able to just replace the plate or even weld in the groves and grind it smooth?? Not using as a hard core quad or anything just want to save a few bucks. Let me know what I will need and if possible help me find a decent price online used on ebay or something so give me a link because I can't seem to find it. So heres the video link: http://www.youtube.com/watch?v=PnYJMo14Z7s Would be best to answer through youtube so it be easier to reply. Hope I can get some help and im new to this and kinda clueless and should stick to the manual gears lol. Well thanks and god bless you!
The problem will be in one of the 2 drive mechanisms,or a simple clutch cable adjustment.First it is a clutch plate driven transmission with a expanding drive sheave.Start where the power is transmitted-are the friction and steel plates in the clutch pac burnt up or is the clutch lever out of adjustment.Check to make sure the clutch lever has about a 1/16 th inch of slack and not pulled tight against the clutch perch.If it is tight give it the right amount of free play and try it again.If that doesn't solve the problem and it still revs high,check the width of the drive belt against a new one as these belts wear out they lose the ability to expand the drive sheave all the way and you lose top end.Now if that isn't the problem the only other place to look would be the clutch plates themselves.Dis assemble and look for blue steel plates as that would be the first sign of a burnt clutch
