The Mikuni RS Series Carburettors were designed and built in response to the needs of the world’s top motorcycle road race and drag race teams. They required carburettors which would 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 high performance use.
The carburettors 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 Carburettors offer superior horsepower gains with their maximum flowing smoothbore induction tract and radial flat slide design. An adjustable accelerator pump system helps to provide instant throttle response, particularly in the lower RPM range. For street bikes the improvement over stock carbs is quantum but most impressive is the smooth operation with no flat-spots or hesitations, just great everyday riding with raw power thrown in when ever you ask for it.
The RS series Carburettors feature a compact design which is 25% lighter than other performance carburettors, offers quick needle jet adjustment, and uses readily available standard Mikuni jets. On street engines, very rarely is there ever a requirement for additional jet purchases with this superior delivery design precisely metered fuel irrespective of what ever the air flow volume or velocity, making these a simple bolt on, hold on and go option weather it be a 750 or 1100cc engine. Carburettors are available in 34, 36, 38, and 40mm bore sizes with standard carb spacing for some Suzuki, Kawasaki, and Yamaha motorcycles. Mikunioz also offers custom make kits for a multitude of different carb spacing and port diameter variations.
