Currently the strongest 4-stroke off-road carburetor.
Simply installing it dramatically improves acceleration, torque, and throttle response! Features a tilted flat valve.
By combining a floating valve (back pressure balance valve) with the throttle valve, it ensures the same ease of handling as a standard carburetor at low speeds (startability, idling performance, anti-snatch performance).
The throttle valve uses a resin roller with built-in miniature bearings, and together with the stainless steel throttle shaft, achieves light and smooth throttle operation.
There is absolutely no sticking of the throttle valve due to negative pressure.
The introduction of a diaphragm-type accelerator pump eliminates stumbling at low speeds.
There is no decrease in fuel efficiency, which is common with tuned carburetors.
FLAT-CR Carburetor Compatibility: SR400/500 (for CV carb models) (Funnel Type)
