We have an '02 Venture 700 touring machine, and it runs great. The problem is that it seems to take a lot of throttle to get it moving compared to our Arctic Cat 550 Pantera. Is this normal, or do we have a clutch/belt problem. When we first got it (used) the belt squeeled so we replaced it, and it no longer squeels. It just seems to take a LOT of throttle to get the sled moving. Any thoughts on this?
