Koso 34mm Throttle Body/Intake Manifold - Honda Grom / Monkey

As the throttle body and intake manifold are used to control the amount of air flowing to the engine’s combustion chamber, they are important elements of the admission system. Using our Koso 34 mm throttle body in conjunction with our 30.5 to 34mm intake manifold will allow better air/fuel mixtures for a quicker throttle response. This kit best benefits high RPM or larger displacement applications. Ensure to talk with your engine builder or tuner if this is a proper direction for you bike. 

Fuel adjustment required.
