Single Bore EFI Manifold by S&S Cycle®. 52mm throttle body is essentially the same size as S&S® Super G carburetor. When compared to stock throttle bodies, the 52mm single bore offers 33% more cross-sectional area than 45mm throttle bodies of 95-05 Big Twin and 28% more area than the throttle bodies in 06-07 models which had 46mm bores. Both throttle bodies use the same manifolds but require different air cleaners. Select the correct S&S® single bore throttle body kit based on your existing stock fuel injection system or the system you plan to use in a custom application. Fuel injectors have an output of 5.12 grams/sec at 58 psi.
