Koso's KSR carburetor features a semi-flat D-shaped slide 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 2 different sizes and easy to adjust and install, this carburetor will allow you to set-up the ideal air/fuel ratio for better performance.
Also includes a NCY Teflon Coated Intake Manifold and a Screened Velocity stack. Free throttle cable included.
