Included in the price of carburetters: installation of any size main jet, needle jet, slide, needle and carb tops that you need.  Specify these during checkout in the order comments section.  You may to be able to find a "cheaper" carb price, but you can't beat doing it right the first time.  Carbs are often not supplied by other resellers with the correct jetting for your particular motorcycle-at Klempf's, we make sure it's right for you.  Also note that $300+ domestic orders receive free UPS Ground (AK and HI excluded).
