2010 Polaris 600 RMK compression

Anybody know what the compression should be on a 2010 600? Mine went down on me Saturday night and I'm going to check compression tonight. Thanks!

Compression should be somewhat equal on both sides. Not all gages will read the same so its hard to say what yours should read. Saying that the compression should be around 110.Pull your exhaust valves and look at the pistons and see if they are scored.

Ok, mag side is 60 psi and pto side is 120. Guessing that's to much of a difference! Anybody know how to drain the coolant on this thing?

Pull the hose off in the front of the motor that goes to the water pump and let her go. The water pump is located under the exhsust "y" pipe.

yeah, I finally figured out to just pull the hose, was just hoping there would be a drain. Its all apart except that I can't get the screw out of the bracket holding the fuel rail and injector on the backside of the jug to pull the jug out. Very tight area to get into and I really don't want to pull the airbox as it looks like a b#%$%@ to get back in.
