Kawasaki Ninja Owners Manual: Throttle Control System

Kawasaki Ninja Owners Manual / Maintenance and adjustment / Throttle Control System

Check the throttle grip play each day before riding the motorcycle, and carry out maintenance and adjustments in accordance with the Periodic Maintenance Chart. Adjust it if necessary.

Throttle Grip

The throttle grip controls the butterfly valves in the throttle body. If the throttle grip has excessive play due to either cable stretch or maladjustment, it will cause a delay in throttle response, especially at low engine speed. Also, the throttle valve may not open fully at full throttle. On the other hand, if the throttle grip has no play, the throttle will be hard to control, and the idle speed will be erratic.
