i bought a 2003 polaris predator, not running. It would run when it was bump started but not start on its own. After pulling the starter clutch i found that was bad because it would only engage sometimes. Checked the valves and they are way too tight to be within specs. Adjusted the valves and then did a compression test on it. The problem I have now is the compression tester read at least 250, a couple different times. What could be the reason why the compression is reading so high? Could a cam be wiped out? I believe the motor has a high compression piston in it but dont know anything more about it.
