Hello, new to this so sorry if I'm doing it wrong but my polaris locked up on me and I can turn both sided of the engine with the sparkplugs out just a little bit. It was over heating while I was riding it and then it just stopped and wouldn't start back up. I changed the starter the and bendix but still will not start. I hear the starter kick but then just stops and the engine doesn't budge. Any thoughts on where int he engine it could be?
