I just did mine on my '99 1500 Drifter, using the method shown on Gadget's Fix-It Page for Kawasaki Vulcans. He has a very easy method that eliminates all the disassembly you normally have to do by installing a grease zerk. Mine must have been nearly dry, it took nearly half a tube of waterproof grease to fill them up. I couldn't believe how much easier it made low speed turns, where you have to turn the handlebars, like when doing a 90 degree turn at a stoplight or stop sign. Just look on the easy tips page, it's about the 4th one down.
