I ended up getting a Tempa-flow instead of Dail-a-Jets. I don't ride where altitude chages affect jetting, so the atomatic compensation for temp changes takes all the worry and fuss out of it. Holtzman also makes a manual system, similar to the Dial-a-Jet in that you have to turn a knob, called a Vari-flow and they know have an automatic device that does both temperature and altitude. I think the web site is somethign like Holtzmaneng.com. The Tempa-flow works great, some of the best money I've spent on my sled.
