NOTES:

  • Twin cam models may need to slightly file down one or more front cylinder fins depending on which intake manifold is used. Easy and wont be seen after install.
  • Choke cable included on most models, except for the 42mm, which can use the stock choke cable from CV-type carb, however the Mikuni choke cable is highly recommended!
  • We highly recommend running an airbox adapter to accept the factory/aftermarket CV carb or non-TBW EFI style intakes. Sold separately.
  • Kits/carbs do not work with cruise control.
  • HSR series carbs use the same throttle/idle cables as the factory Harley CV carbs on all models except sportsters. Sportster will require the use of Big twin style cables.
