my new set up is gonna be a 4 mill, .40 over, shaved head, dune port, cpi pipes with pwk35s. all my friends are pretty dam good riders. they all race motocross. every time ive ran a banshee in the past on my CRF ive killed it. the last one i raced was stock stroke ported, shaved head, T5s with stock carbs. i put about 7-8 bikes on him.
