I am building an engine for my 2002 banshee and I bought a new coolhead with 16cc domes. I have ported cylinders, vitos power pistons, .60 over bore, v-force 3 reeds, 28mm pwk carbs, t-6's, and adjustable stator plate. I do mx and trails with my bikes and I am at about 500ft above sea level. I wanted to know if the domes that came with the head are to small even with 120 octane fuel.
