I have a 2004 Polaris magnum 330 automatic 4x4, was riding this atv when the atv fell flat and powered off after I powered the atv back up, it no longer will run past 3k rpm’s and will not show it is in high even with the shifter in the high location. The atv was at my local Polaris dealer for over 3 months the best they could come up with was that it is blown up, which really doesn’t make sense since it will run like a top under 3k rpm’s, and only bogs down past 3k (doesnt knock or tick) any input on this would be greatly appreciated, thanks
