S&S continues the success story of their Super E and G carbs with a special Black Series edition that was first released for the S&S 55th Anniversary in 2013. These carbs feature a distinctive gloss black Enduraguard coating, which is heat and chemical resistant. In addition to cool cosmetics the Big Bore versions have specially machined venturis for up to 7% more flow. The Black Series carbs are not offered as complete kits, but as carburetor only. That gives you complete freedom to work with these carbs in any custom application. The Super G versions are recommended only for racing applications or engines with 1600 ccm and more.
