Hey guys, I have a 03 pro-x 800. It was running great earlier today and I was working her pretty hard in the fresh powder. All of a sudden it will rev up to around 7000 at 5 MPH. I thought maybe my belt was slipping (almost brand new) but it's not. Any ideas on what's goin on? Also it seemed both clutches especially primary was very hot. I let it cool down for a few hours and the first 5 minutes it's fine but then it starts revving really high again. Thanks for any help guys!!
