R&D Racing Power Bowl


The Power Bowl from R&D Racing is an innovative fuel supply
system float bowl with an anti-cavitation accelerator pump and
adjustable leak jet. Designed for the Keihin FCR-MX carburetor, it
is bolt-on and requires no modifications. Features include:
• “zero tolerance jet chamber”
Minimizes existing clearances eliminating the possibility of fuel
evacuation from around the main and pilot jet area. (no bog)
• “ANTI-CAVATION Accelerator Pump”
Designed with two seperate fuel ports. Port one is positioned at
the highest point in 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.
• “EXTER NALL Y ADJUSTABLE LEAK JET”
Quick and easy hand adjustment for fine tuning.
Available for all 4-stroke MX machines with Keihin FCR-MX
carburetor.
