I just bought a used 2001 Polaris TrailBoss last Friday. Overall, I love it for where/how I ride. When I first start it up, it seems there is a noise coming from under the black plastic cover like the belt is rubbing or something. After riding for a few minutes the noise goes away, and doesn't return until I start it the next day. Any ideas? Thanks[img]i/expressions/face-icon-small-confused.gif[/img]
