We have made 50 of these and 50 only. These will never be reproduced. This is the wiring plug that goes through the cases and holds your stator wiring.
Normally these units use a different thread than all the other wiring plugs on the Kawasaki. We changed it to use the same thread so all your aftermarket billet nuts you use on your Kawasaki electrical boxes will fit. Unlike the original baker-lite ones you normally have on your 550 these will not crack and break. Get them while you can
