So my 450xp seems to be hanging just a bit in the 15-20mph rang! Also when i give it hell i feel a bit of a grumble in the assend and it seems to slip a bit like not getting power to wheels? Going to check belt that has like 1800 miles on it i think will check! But anyother ideas beside a belt check and a cluch cleaning? Any help or advice wld be great TY

 

450xp??

yeh, I would check the belt, with 1800 miles it wouldn't be a bad idea to check, even if it isn't bad, I would also clean up the clutches
What year is your bike?

 

Worn cluch buttons is a common problem for that symptom,but cheap and easy to fix. But start with the belt.

 

Lol had the xp on my mind! funny! Ya no its a 2007 450 sportsman!
