Bikeman Performance Polaris RZR 900 Ported Head Kit

Bikeman Performance Polaris RZR 900 Ported Head Kit

Are you looking to get the most out of your RZR? This motor kit has been proven to produce actual results that make big horsepower. On the national racing level, this package outperforms so much that competitors have tried to tech us for cheating. NOPE! It's simple... the homework has been done and we've created the most badass engine package available. The stock platform is alright, but they left so much airflow on the table. We start off by changing out the small exhaust valves with larger ones, then porting your head to our proven specs.  We then add our high-performance camshafts which have a higher lift and a great profile to make huge all-around horsepower gains. Next, we add heavy-duty valve springs, valve seals, new spring bases, retainers, HD 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. All you need to do is simply install the head and time your cams. The kit is meant to run with 91 octane pump gas, no race gas required.
