Welcome aboard? Do yourself a HUGE favor and get a Kawasaki Service Manual. They are worth their weight in gold, and no one has ever regretted buying one. They usually are available on eBay; be sure to get the one for your bike's exact year and model as there are differences. In the meantime, you may find the info in the link below helpful.
