Change yur belt jmax.
Yes. Tried 3 different belts in 2300+ miles. My 2nd belt I thought might have been the fix but it turns out that I only got 100 miles or so before the issues returned. I put in the SLP Stage 2 kit and got 1000 miles without problems but then the RPM issues came back with a vengeance. That's when I let my dealer have a shot at it. They looked at all of the Polaris so called possible problems that contribute to RPM issue. They found nothing and None of that helped anything. I think it could be Clutch related? Heat is also another of my thoughts? I believe that it is a complex bundle of several different problems contributing to the problem.
Although I'm sure as "RATCHIT" put it. I'm just another person that knows nothing. Somebody must have sneezed on me on the H.C.S site.
I know that there are people that like to stir the Pot and create stupid stories. I also know there are people that will read some of the RPM issues and begin to believe that they also have problems. Some people probably only need a new belt and think they have the issue. I'm not one that has nothing better to do than try to stir the pot and create havoc. I rode a Pro-R 800 for two years and had zero issues. I never once hit the forums with a single complaint or negative comment.
Seems how this post was answering a question someone asked if I changed my belt I'll add this comment. All 3 belts that I swapped out all looked fine. I used to change belts when they started to look worn. Cracked, frayed or simply blown apart. Not the case with these new belts. Might look a little glazed but other than that they looked nearly as nice as the new one being put on. So now I have 3 belts that look fine. One with 700 miles, one with 1200 miles and one with 400+ on it. I put the 1200 mile belt back on the traded in sled and kept the other two that had less mileage on them. Couldn't tell you if they are good or bad? I just know that they didn't fix the problem.
As far as clutching being the problem?? I avidly clean the faces of the primary every 200-300 miles and lightly scuff the belt then clean with warm soapy water. I've changed the primary spring. I've changed the secondary spring. I've changed the weights. I'm not a true mechanic -nor- do I want to be. I haven't checked alignment or any of the more technical stuff. When running good she turns 8300 consistently sometimes pulling up to 8400. When running like a turd I've seen her top out at 8000 and be that way all day. When having a real bad day I've seen 7400 as a peak. 8000 rpm is annoying as ever BUT anything under 7800 just down right pisses me off. At the end of one of those days you could say I'm pretty dam bitter. Most of the season it was like a light switch going from good to bad several times a day. At the end of the riding season "Last 200 miles" it was consistantly low. 8000rpm was as good as it would get and 7400 was there for 50% of my riding.
THIS IS WHEN I DECIDED TO TAKE A $4,300 BATH AND TRADE IN. I JUST COULDN'T START MY NEXT YEAR ON THIS TURD. I SPEND ALL SUMMER LOOKING FORWARD TO SNOW RETURNING AND RIDING TO START AGAIN. I WASN'T GOING TO SPEND ALL SUMMER BREWING OVER IF MY SLED WOULD EVER RUN RIGHT AGAIN.
