Dealer Only Item

Facebook Twitter

Similar in construction and use many of the same parts found in S&S® gasoline carburetors, the S&S carburetors for race engines are designed for applications where a gravity feed fuel delivery system is used. The use of a fuel pump is not recommended as the fuel inlet needle and seat assemblies in these carbs are not capable of handling additional fuel pressure.

  • Available with standard 1.937" venturi or larger 2.150" venturi
  • Features an enrichment starting system
  • Recommended for use on large displacement racing engines (not recommended for most street applications) – Low rpm throttling and midrange response is poor on stock displacement engines

NOTES:Manifolds must be ordered separately.
An S&S teardrop air cleaner is available for those Super D applications that require an air cleaner.
If Super D carbs are used on 1991–later Harley-Davidson® Sportster® models, 1992–later Evolution® big twin, or Twin Cam 88® engines, head breather hardware must be fabricated.
Once a Super D gasoline carburetor has been converted for use with alcohol, it may not be used with gasoline afterward.
