If you are overhauling the gear selector and gear change assemblies, the associated parts are better being renewed, preferably replacing all the interfacing components at the same time - mixing worn parts with new may lead to premature wear of the new item; even the knowledge that old parts have been reused can be stress inducing!

This component may have other applications within the Kawasaki model range - so please ensure the part-number ordered is correct for your application.
