Racetech Gold Valves work great. I have used them on a couple of my Kawasakis. You buy the kit, and in the kit is an access code. You go to their website, type in your access code and all your rider information, and the computer will magically come up with your valving codes. Be sure to have your master code sheet in hand when you go to get your shim stack codes, so you can circle the formulas that the website gives you. You can't go back in a second time. The valving is very plush and yet plenty firm.
