Currently the strongest 4-stroke off-road carburetor.
Simply installing it significantly improves acceleration, torque, and throttle response! Features a tilted flat valve layout.
By combining a floating valve (back pressure balance valve) with the throttle valve, it ensures the same ease of handling as a standard carburetor in low-speed ranges (startability, idling performance, anti-snatch performance).
A resin roller with built-in miniature bearings is used for the throttle valve, and together with the stainless steel throttle shaft, it achieves light and smooth throttle operation.
There is no sticking due to negative pressure on the throttle valve.
The introduction of a diaphragm-type accelerator pump eliminates hesitation at low speeds.
There is no decrease in fuel efficiency, which is common with tuned carburetors.
