I was wondering if any one knew if putting a cool dome head on a 250R would help. I saw it in Rky. Mtn ATV and was just curious if anyone knew anything about it. I already have several aftermarket parts on my R(wiseco piston, boyesen rad valve, jetted,esr exhaust TRX6 pipe, twin air filter running open top). Just wanting to get some opinons before i spend close to $200 on this. I have seen them on banshees but not on an R. The product is made by pro-design, also what CC should I put on it. Someone told me that elevation made the difference in what CC you put on it. Were about 2650 feet above sea level. Thanks
