Bikeman BIG VALVE AIRXTREME HEAD KIT PRO R
Are you looking to get the most out of your RZR PROR? Our BMP kit has been proven to produce actual results that make big horsepower. The stock platform is okay but they left so much airflow on the table. We start off by changing out the intake and exhaust valves with larger ones then CNC porting your head to our proven specs. Next we add our BMP high performance camshafts which have higher lift and a great profile to produce more all around horsepower and torque. We then add heavy duty valve springs, valve seals, retainers, shim under buckets, and shim your valves. This means we switch you out to a regular shim under bucket style adjustment and we do the valve shimming for you so your head is ready to bolt on. Kit is meant to be ran with 91 octane. If you would like to run race fuel, please let us know and we can include a race fuel map. ECU must be sent in
