1981 Honda CB900C Custom · Carb Floats & Small Parts Buying guide
The 1981 Custom has a separate fuel-line diaphragm in addition to the accelerator pump and air-cutoff valves. A dry bowl, an overflowing bowl and fuel leaking between carburetors call for different checks. Locate the fault before buying a float or diaphragm kit.

Honda calls for inspecting the float valve and seat for grooves, nicks and deposits, and checking valve operation. A new float cannot make a damaged seat seal. The original float-level procedure measures with the float just touching the valve and calls for replacement if the level is out of specification; do not improvise a bending adjustment.
The twelve-ring package serves fuel connector and accelerator tubes between the carburetors. Renewing those seals involves careful rack separation and reassembly, followed by checks for free linkage movement and proper adjustment. Bowl and drain-screw seals are separate. Compare the original fasteners by position before deciding how many two-screw packs are needed.
Not necessarily. Inspect the needle, its seat, debris in the fuel supply and free float movement. Honda’s float-level check determines whether the float itself needs replacement; fitting a float without finding the cause can leave the leak unchanged.
They seal tubes between carburetor bodies, so access requires careful separation of the rack. Preserve linkage and spring positions and follow Honda’s reassembly and synchronization checks. The twelve-ring package is not a float-bowl gasket set.
No. Honda documents the fuel-line diaphragm separately in the 1981 supplement. The featured pump kit contains a diaphragm with rod and bellows rubber for the accelerator pump. Identify the assembly and its hose or linkage connections before choosing a kit.
