Sled is jerky

So my 04 Polaris 600 edge touring started riding really jerky the other day. It doesn't want to pick up speed and if I try to go faster the engine bogs a little. I can also smell a bit of belt burning. Correct me if I'm wrong, but I'm thinking the problem have something to do with something in the chaincase? It's like there's too much resistance from the track/chaincase/jackshaft. Need help where to look first. Thanks

By the way, it started doing this after I was stuck one day and went in forward and reverse a bunch of times trying to get out

You possibly need a new belt, that might be it. I have seen where the wrong belt size can make your sled run like there is something wrong, no power,etc. but you may have burnt your belt getting unstuck.

I'm with Detrik on this one. I would examine the belt, looking for any spots that are glazed and damage on the sides.

If you can prop the rear of the sled on a stand, you may be able to see if things are rotating smoothly. But I would look at the belt first.

I partially took apart my primary clutch and cleaned the weights and pins because they were a bit sticky. They aren't worn and they move freely now. I put a new belt on it and run it with the back up in the air. It runs smooth and I don't feel the jerks. When I ride slow, I can feel a definite jerk every few seconds. When I go faster, it turns into an extra vibration. What would cause that? Just looking for answers without tearing apart the whole sled. Would a bad bogie wheel bearing cause that?

Check your drive shaft bearing.

with the track in the air, motor off, try rotating the track by hand. Feel for anything unusual.

The track will rotate by hand and doesn't feel like it binds at all. I checked the driveshaft and jackshaft bearings and they are all great. I did have my secondary apart a few weeks ago and I noticed that the large washer (not sure right terms) that the tensioner bolt pushes on had worn a bit into the sheave where it contacts it. Could that cause a jerky feeling when going slow and vibration when fast?
