When building a Yamaha R3 Superbike, air flow becomes a problem, and overboring the throttle body to increase flow is the cure. We have dyno tested performance with straight bore and tapered bore throttle bodies and prefer to use the largest straight bore throttle bodies for maximum performance. Our Yamaha R3 throttle bodies are bored 1.5mm over the OEM size to increase air flow. New butterfly valves are installed and additional proprietary changes are made to increase air flow based on our own dyno testing.
