KOSO Honda Grom/Monkey 34mm Throttle Body

The KOSO 34mm Throttle Body for the Honda Grom and Honda Monkey. The throttle body is key to controlling the amount of air capable of flowing into the engine combustion chamber. This is extremely important for a bigger bore or high compression engine. Having a larger throttle body will provide quicker throttle response and properly balance out the air to the fuel-air mixture. This is most commonly used with the KOSO 170cc Big Bore and the DROWsports 181cc Big Bore Kit. Please be sure to purchase the additional Brass Air Screw mixture for easier tuning and adjustment.
