big bore is more designed for modified motors, I have one and can tell you it lets the motor really rev high and has plenty of power, I don't have an OBR but I have the stock, 29cc that was ported to 30.5cc, also the stock 6000rpm clutch but it does have one heck of a top end.
I have no words.
VRC Pro pipe? How different would it be with the VRC Big Bore?
