Today I was out riding . Came out of a trail on to hardpacked road , Nailed the throttle for about 3-5 sec. When I let off It sounded like something let loose. I stopped checked to see if I Blew a belt. Couldn't find anything . Started again, same thing happened. This time I could feel it. The sound seemed to come from the clutch side. Checked all clutches. The only thing I found was the drive clutch had some marks in where the spider cames out. Babyed the sled back home tried it one more time and nothing bad happened. Checked everything out can't find nothing. Is it possible the probllem possibly in thedrive clutch? What ever it is it doesn't feel good!!!!!!!!!!!
