i didnt read this before..but i disagree..my brothers old setup was a stock stroke eric gorr woods port. 33mm pwk, t5's, stock airbox, noss head with 19cc domes..this setup made excellent power and torque. this bike was awesome in the trails. it was a stock length swingarm bike and it handled fine. the power was perfect and i could ride that bike just as easily as a new yfz450. you most definetely CAN set a banshee up to be an awesome trail bike. sure, its no yfz450. but you can make a banshee a great trail bike, just not with a set of cun cylinders..remember, they are NOT trail friendly!! :thumbsup:
