***You will need to replace the start/kill switch when you install the Domino Race Throttle Kit on your Kawasaki Ninja 400 because the OEM start/kill switch is part of the throttle housing. There are a few options available for this: The Domino Kawasaki Ninja 400 kill switch is an inexpensive, plug-and-play replacement switch for the Kawasaki Ninja 400. The Kawasaki Ninja 400 Kill Switch w/ Integrated Keyswitch Elimination Harness is a plug-and-play harness for the Kawasaki Ninja 400 that also bypasses the OEM keyswitch so the heavy keyswitch can be removed. This is recommended for racers, as it’s a better and cheaper option than purchasing a Kill Switch and Keyswitch Eliminator Harness separately. *This kit is for closed course use only.
