Mikuni RS 34mm Carb Kit – Honda DOHC CB1100 | 1979 and Up

Unlock the full potential of your Honda CB1100 with this Mikuni RS34 Carburetor Kit, designed for models with stock DOHC engines. These genuine Mikuni flatslide carbs offer precise fuel delivery and smooth throttle response, resulting in a power increase of up to 25% with no hesitation or flat spots.

Kit Highlights:

• Brand-new rack of Mikuni RS34 carburetors – jetted and ready to install

• Optional throttle and cable set available (select from the dropdown)

• Filters sold separately

• Includes correct spigots and hardware per spacing option

Performance Upgrade: Rebuilding OEM carburetors can be costly—and risky if aftermarket parts are used. This RS34 kit is a modern, bolt-on upgrade that provides better performance, reliability, and value for CB1100 riders looking to enjoy their motorcycles without compromise.

Important Fitment Notes: Before ordering, please verify your carb spacing and engine setup. This kit is not compatible with downdraft engine configurations. Two spacing options are available:

Installation Tips:

• Stock throttle cables are not compatible—optional throttle/cable kit recommended.
