I have a 2005 sportsman......and im not really sure whats wrong with it except... when it hits 20 mph.... it sounds like it revs up... and stays at 20mph until i let go of the throtlle then press it again then it goes past 20mph usally it jus easly goes past 20mph right away with out the stall at 20mph...anyways does any one perhaps know whats wrong? or if theres anything...

 

guessing theres a secondary clutch problem.

 

I agree with sendori. My 95 had nearly the same symptoms and it was the secondary (driven) clutch. However, I'm not sure if our clutches are the same.
