Hey guys i have another build im starting soon, id like to build this engine a little more than the one i just finished- stock engine and carbs, +4 timing, reeds,fmf pipes/silencers, bored .60 over. The next one i am thinking 4mill or get it trail/play ported. Which would be the best bang foe my buck and reliable for trails. 4mill require new or shaved head, bigger base gasket and a 4mill welded crank? Anything else?
thanks
