Hi there, i'm new to this forum. I've got a 2003 Sportsman 500 HO, it has 1700 miles on it, hasn't been out of the yard in 4 years, been mainly used for plowing driveway. This past weekend i took it to a friends cottage. Alot of the water holes weren't frozen enough to ride on top, so we were breaking through the ice alot. When ever i went through a water hole that it was a little over the floor boards, bike would rev up like something was slipping, it would barely crawl along, but once i was out of the water, bike pulled fine. My first instinct was that my belt was slipping, but if it was the belt slipping from being wet, why would it not keep slipping after it came out of the water hole. I would assume that once the belt got wet, it would slip for a while. Anyone have any ideas?
