Rzr in high gear or low gear revs to 7700rpm will rise to about 8000 to 8050rpm Max… Neutral will rev to 8900rpm … My mods hmf full exhaust, k&n filter, dobeck a/f tuner, Dalton clutch kit, 32″ pro armor crawlers… Was doing exact same before clutch kit, also have put fuel gauge on fuel rail and ran down the road wide open holds right at 59 to 60psi .. Clutch kit was last thing I did. My rzr when I bought it used to do 8750 to 8800rpm in high gear.. I’m out of ideas on why this is happening, it also was doing this before 32″ tires and the tires did not change the wide open rpms..
