We don't know what type of tires the OP is using, what type of riding, etc. The Stan's tubeless system is great for off road riding from my experience, but only if you want to run your tires at relatively low pressures. Anything over forty or forty-five pounds, the Stan's sytem isn't recommended-
edit: For the OP, I just checked the Stan's NoTubes site, they do carry a special injector that will work for putting the sealant directly into valve stems, whether a tubeless tire, inner tube, etc. according to the info given, as long as the valve core is removed-
