R&D Power Pump.
Why spend hours adjusting your jetting, R&D Racing's new
Power Pump will allow you to tune your accelorator pump
setting in seconds, for that crisp spot on throttle response
you are looking for.

Our ''ANTI-CAVITATION'' Accelerator pump is State of the Art, designed with two separate fuel ports. Port one, is positioned at the highest point in the fuel chamber, providing a natural purge, allowing entrapped air to escape through the leak jet orifice. Port two, is isolated low in the fuel sump area, assuring 'FUEL ONLY' into the venturi. FITS ALL FCR-MX CARBS!!!!
