i dont have this but i know alot of people are going with the wr crank setup to get up to 449cc, and also ive heard the "oiling mod" will help you motor last longer

oil mod is a must for high comp. pistons cause on the 04 and 05 the rods where breaking the oil mod gets more oil to the crank so everything runs smoother. But all you need is port and polish your head, retard you exaust cam 1 tooth, good after market intake, and exaust and save the money high comp piston just makes it hit harder so if thats something you cant live with go for it. On the gas til you see god then let off

i decided this year to do the wr, from what i have heard it rocks, very anxious to get it done so i can see for myself
