I Have a 03 Polaris sportsman 500. I replaced the camshaft and rocker arms. Because of the usual symptoms of acting like the engine rev limiter was active in fwd gear. However it doesn't seem to be active in reverse. after finishing the repair the problem still exist.. anyone run in to this problem? Anyone have any ideas on what else could be the culprit? I'm pretty sure the camshaft wasn't the problem. Any help is appreciated. Thank you.
