Koso North America KSR Carburetor 32mm

The KSR carburetor is based on PWK carburetor core but adapted for 4-stroke engines. It features a semi-flat D-style throttle valve that increases the fuel flow for a better throttle reaction. It also reduces the incomplete combustion phenomenon, and therefore improves the combustion efficiency. Available in 4 different sizes and easy to install and adjust, this carburetor will allow you to set-up the ideal air/fuel ratio for a better performance.
