The Mikuni RS series carburetors were designed and built in response to the needs of the worlds top motorcycle road race and drag race teams. They required carburetors which could satisfy the precise fuel metering demands and high flow volume required by highly modified race engines. And yet, also provide the smooth controllable throttle response that is needed by any rider pushing his motorcycle to its limits on the race track and under any high performance applications. The carburetors need to meter fuel correctly under a wide range of atmospheric conditions and engine tuning modifications while being easily accessible for trackside tuning changes which need to be made quickly.
Designed for in-line four cylinder performance motorcycle applications, the Mikuni RS series radial flat slide carbs offer superior horsepower gains with their maximum flowing smoothbore induction tract and radial flat slide design. And adjustable accelerator pump system helps to provide instant throttle response, particularly in the lower RPM range. The RS series carbs feature a compact design which is 25% lighter than other performance cabs and uses readily available Mikuni jets.
Starter System: Provides fuel enrichment for cold engine starting
Adjustable accelerator Pump: Adjustable accelerator pumps system helps to provide instant throttle response, especially in the lower RPM range
Accelerator Pump Adjust Screws: Sets on and off operation of accelerator pump in relation to throttle slide position.
Idle Adjust Screw: Controls engine idle speed
Throttle Return Spring: A choice of positioning pegs allows adjustment of spring tension
Pilot Air Jet: Use in conjunction with the pilot fuel screw for tuning of mixture at idle to 1/4 throttle
Smooth Throttle Bore: Produces the optimum air and fuel mixture flow at all RPMs
Accelerator Pump: Shoots fuel directly into the intake tract for immediate engine response
Flat Throttle Valve: Provides the strongest signal for precise and instantaneous throttle response
