Honda CB Carburetor Floats & Internal Parts

Carburetor floats and related internal parts help regulate fuel within each float bowl. Deteriorated seals, damaged floats, hardened diaphragms or worn drain components can contribute to leaks and inconsistent fuel control. Replacing worn parts with components suited to the original carburetor helps support dependable operation and accurate fuel metering.

This collection includes carburetor floats, pump diaphragms, air-cut valves, fuel-connector O-rings, drain screws and seals, overflow hoses, accelerator-pump hoses and float-level gauges. Honda used different Keihin carburetor designs across CB models and production years. Compare the carburetor application, dimensions, included pieces and OEM reference shown on each product page when choosing replacement parts.

For complete kits, jets, needles and bowl gaskets, browse our Honda CB carburetor rebuild and jetting parts. Replace deteriorated intake connections with carb holders, air-box boots and clamps, or find measurement and adjustment equipment in carburetor service tools. You can also return to the complete Honda CB fuel-system collection. Use the My Motorcycle selector to display products listed for your Honda CB model and year.
