IDLE SCREW TPI THROTTLE BODY

The idle screw modification allows riders the ability to adjust the idle on their KTM, Husky, and Gas Gas 250-300 TPI 2018-2023 dirt bikes. 

By having an actual “adjustable” idle screw, this allows riders to use the air mixture screw on the side of the throttle body, as an actual adjustment to modify the air/fuel mixture flowing through the throttle body. 

The air mixture screw provides adjustments to richen or lean the air/fuel mixture, enhancing overall throttle response and engine performance for individual rider preference.  Turning the air screw “in” (clockwise) will richen the air/fuel mixture.  Turning the air screw “out” (counter-clockwise) will lean the air/fuel mixture.
