Recently just got my 2016 rzrxpt back from getting all recalls done. Went for a ride and as soon as I hit about 68 or so it started falling flat on its face and it wouldn’t go any faster than about 72 mph. What could be causing this? Is it the new clutch spyder they put in or does it have to do with the reflash? Had the evo stage 3 before and the car absolutely ripped before.
