I have a 2009 700 RMK wth 1400 miles on it that ran perfect last year. I started it up and loaded on my trailer to go out west, still ran good. When we arived the sled didn't want to idle correctly. I ran a new tank off gas through still would not ideal correctly. I then brought it to the polaris dealer in Dubois WY. He checed the TPS, Voltage regulator and ECU. Still would not idel. Found out tha i had a cylinder that was at 75 lbs Compression. Does anyone Know what is the most likely cause for this and what do i need to look for when i rebuild it?
