I'm putting a mikuni 42 mm carb on my Harley softail standard
By Jeff
Do I need this flange to help my throttle cables return or is there something else
Answer QuestionThis adapter allows the use of an HSR-42 on early two bolt style manifolds found on Ironhead Sportsters, Panheads, Shovelheads and early Evolution Big Twins. Depending on the air cleaner assembly you wish to run addition parts may be required. We also have complete kits with air cleaner and manifold, you can find that kit in our store by searching "Mikuni HSR Total Carburetor Kit with Manifold" in our store search bar.
