Clutch/Belt issues with new 1000 S

Hello everyone, I just bought a new 1000 S. Glad to join the small group here. Had a Rhino since 2005 and finally took the leap. I mainly do trails in Moab.

I have a couple questions you all more familiar with Polaris may have ideas on.

1. The clutch seems a little jerky in reverse especially at lower rpm. Is this normal? It is very different than the Rhino every where in that the rpms come up quite a way before engaging. However reverse seems even more strange with the jerkiness.

2. I burnt a belt already. Got a little smoke and can see the sides of the belt grooved and glazed in a spot. Working on repalcing and the manual talks about ebs vs non-ebs. For ebs it says to use the clutch spreader tool to open the clutch. For non-ebs it says to loosen the nut to spread the clutch I am unsure which method to use. It sure feels like I have engine braking, but the web site says I dont. I am wondering if anyone knows for sure the best way to open the clutch on this to remove/replace the belt.

Thanks,
Keith
