i am presently rebuilding my motor and wish to had a little power to my shee. The thing is i really need to fuel up with pump gas (91-94) octane. I ride wooded trails and forestry road most of the time. presently my mods are: v-force 3, k&n filter, fatty fmf and power core 2, boost bottle, stock carbs, dynatek cdi set to map2, ricky stator and aluminum oversize radiator.. i'm Running 40:1 mix with Klotz ONLY .
I will install a cool head and welded and trued my crank cause it's still good ,but Which domes would you suggest? to get about 60-65 hp do i need porting? Remember that i really neede to stay on pump gas
thanks guys
