Oh God, Don't get me started !!!! Go to "Dragspecialties.com" look under "air and fuel" look for your carburetor, (Kei Hein CV type, or whatever) write down the "DS" number, call your local Harley Davidson shop, they will have them in stock...Please don't go through what I just went through (see "Performance mods", "Pilot jet nightmare")...I have tried "newspeedmaster.com" but suddenly had "mysterious charges" appear on my credit card bill shortly afterwards...
