Hi. I have a 2000 Trailboss 325. I was turning on a different trail yesterday and there is a bit of an incline but nothing I couldn't handle in the past. I was going up it at a slow pace cause I just turned. It proceeded to lose momentum and roll backwards and I had to break hard. My buddy was riding behind me and we were both confused what had happened. I tried again with caution ready to stop myself and there was some smoke coming out both sides kind of from in front of the engine. I thought at that moment I had water in the belt box from a creek a ways back but it wasn't acting like it usually does when I get water in there. I backed up and got enough momentum to get up. Keep in mind that the engine was running fine and didn't bog. I wasn't far from home so I went really slow. Today I started it up and drove it to the garage from the backyard and it still lost power trying to get up certain parts of my yard. I now have the belt box off and the clutch looks fine and the belt looks fine. What should I do?
