This manifold for 1994–'02 Harley-Davidson® Buell® models is a stock (4.650") length manifold for S&S Super E carburetors. Note: S&S manifolds for Buell models are not interchangeable with manifolds for Harley-Davidson® Sportster® models as they position the carburetor about 1/4" higher. This change in position will cause misalignment of mounting hardware.
