zacdog 10 Report post Posted April 19, 2008 We just got a Polaris 500 Predator yesterday, and today it started missing really bad, and there was a significant amount of oil in the air filter box. No smoke is coming out of the exhaust. Please help as to what you think it might be!!! Share this post Link to post Share on other sites Like what you are reading?
