hey NC was that a race gas kit w/intercooler. if so i have the same kit on a 2010 800. i ran it last year here in sd. i ran a 11to1 PA head on mine and got along great. ran <5 lbs didnt want to push it on 91 octane. tore it down this year put the 12to1 PA head in and fresh pistons. mine seemed to rip last year. hope yours does too.
