www.kawasaki.com bookmarked for parts number search.
www.kawasaki.com have detailed parts diagram/listing, with up-to-date year models.
i check there to see the latest parts number. sometimes i use it to get an idea what are the latest "bug fixes" for any particular area of the bike that i might be working on in future. new/replacement parts are indicated with a red mark on the parts listing.
navigation-wise, on the left side of the website, go to "owner info" --> "parts diagram".
