To mark their 55th Anniversary in 2013, S&S created special, limited edition, Super E and Super G Shorty carburetors. In addition to cool, cosmetics, these carbs had enlarged venturis for up to 7% flow. By popular demand S&S has added them to their regular range of products. Not available as a kit, but as a carburetor only. These Super E and Super G's feature an exclusive heat and chemical resistant black satin Enduraguard coating.
