Hello, im posting my third post now about problems with the new 850. I got an sks 850 146, when i give it half/full gas from a stop it sounds like the track is loose or something in the chaincase like its just spinning. Do i just need to tighten the track or can it be something else?

It's probably spinning the drivers on the track (ratcheting). Tight the track to Polaris specifications (see owner's manual for this).


Depending on how many miles/kms you have, checking the chain for proper tension/tightness may also be needed, but I'd check the track first, the tracks stretch a lot in the first few rides.

You need to check and adjust drive belt deflection, chain tension and track tension on a new sled. They will all break in/slack off to some extent. The drive belts loosen up a lot in the first ride or 2 on 850's.

Go buy avid extrovert drivers and eliminate one issue for good. Plus you reduce a tremendous amount of rolling resistance. You won’t be sorry!
