Many are reporting backfiring, others are not. Although they are fuel injected, I wonder if there is a correlation with elevation and ambient air temperature like what would be typical with a conventional carburetor.
If Polaris sets them up lean to help pass emmisions or whatever, wouldn't there be less likelyhood of backfiring when ridden at higher altitudes and/or warmer air temps?
So to explore this theory, please reply if your 570 backfires or not, and what elevations and air temps (ie warm, hot, or cold) you typically experience the backfire (or don't). - thanks!
