If you don't have a copy of the owners manual, you can read it for free at kawasaki.com. You should be able to download it or print it out. It's not in one big pdf file, though; it's in about 17 smaller files. Open up each pdf, then save a copy from Adobe Reader by using the "floppy disk" (save) icon. You can also print it directly if you like.
To get there you have to jump through a few hoops. Once you're at kawasaki.com, go to Owner Info --> Owner's Manuals, then click through a few screens to your year of bike, then click Owner & Service Manuals. You'll finally get to Download Manual. It's the same place you go if you want to buy a Service Manual.
