why not print out a nice Kawasaki logo and epoxy it there.
btw when I replaced my own motorcycles ignition switch which was not sold as a new part since a decade, I bought a junked one opened it up keyed it to my old genuine Yamaha key and was good.
btw - never use regular grease in the switch, a long life silicone grease is required or a wax - reason to use them is due to water intrusion and condensation.
But still - the amount of precision you exercise
