QUOTE (RK Tek @ Aug 18 2008, 08:03 PM) index.php?act=findpost&pid=8495Believe or not.. a CR 500 properly ported, headed, with an FMF pipe will touch on 90-100HP on pump gas!!

By looking at the cylinder one would think that it is not possible to extract that much power from an ancient cylinder design.. BUT.. it turns out.. it is possible.. A properly set-up CR500 is un controllable on the dirt and a blast in the dunes..

I think if you added a better designed cylinder (CP INd) yo would surely require a whole new pipe to fully take advantage of the better flowing cylinder..

Again,, stock jug.. BIG power when done right..


Who do i need to contact about building one of these monsters?
