Today I was riding and I pressed the shifter down to go from2nd to 3rd and when I did I still have the quad revving high. It revved higher and then when I let it go it clunked and then took off. The quad seems to shift a little harder now like there is some resistance now and I have to press down harder and when I do it seems to jerk. Can somebody please help? It is a 2003 400 manual straight axel.

 

If its still in the warranty, take it back. That and someone will be by and let you know. sorry I could not help

 

I agree, dealer if its warranty. i think the return spring gets jammed. or a fork jamms for a sec.
