Mikuni RS Series Radial Flat Slide Carburetors

Designed for in-line four cylinder performance motorcycle applications, the Mikuni RS series radial flat slide carburetors 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. The RS series carburetors feature a compact design which is lighter than other performance carburetors and uses readily available Mikuni jets.
