Intake manifold for carburetor on 2007+ EFI bikes
I'm aware that there is a difference in shape on the 2007 and later EFI heads for the intake manifolds, as compared to the 2004-2006 rubbermount sportster heads. As a result, a different manifold is use for late model sportster heads when using a carburetor.
Any recommendations on where to source the correct width manifold for late model heads (which were originally designed for EFI) when using a carb as the fuel delivery source? Any other considerations I'm missing? |
I believe Hammer Performance makes an intake manifold for this application but they are billet aluminum and therefore pretty pricey.

For the stock CV carb option I don't think the Hammer Performance intakes are ported. Not a budget option really I guess.
Sporty Parts has a cheaper option. |

Sporty Parts has a cheaper option. @aswracing , can you confirm that the Hammer Performance intake manifold is US made? Also, I started a a thread here trying to figure out which gasket set to use with EFI heads on an 2004-2006 engine. It seems to make sense for 2007+ gaskets to be utilized, but because there's a non-standard part in the mix (i.e. the Hammer Performance intake for carbureted engines) I wanted to make sure I ordered the correct gasket set. @aswracing , can you help provide insight? |

Absolutely, positively, and I'm not guessing.
Choose your top end gasket set based on what rocker boxes you're using. Although all the bikes from 1991-2022 use the same rocker base gasket (the one between the rocker box and the head), the rubber pieces are very different for the 1991-2003 (3 piece rocker boxes) vs. 2004-2006 (2 piece rocker boxes) vs. 2007-2022 (also a 2 piece rocker box but different). Just spoke to Lorie at Hammer Performance to place an order. |
