- 2011 Assault Switchback
I have a 2011 Assault 800. I had it up in the U.P last weekend and it was running fine. Now it seems to be running on 1 cylinder. Was thinking i just got a tank of bad gas so i drained it and still seems to be missing. Did a compression test yesterday. when i tested it cold each cylinder has 120psi. I ran it and got it warm and retested and it shows 60-70psi. Any ideas? Does it need new rings? can it be anything else?
