1971 Honda CB500K · Fuel System Buying guide

Work from the tank, carburetors and intake fitted now

Separate tank hardware, carburetor internals and intake rubber before assembling an order. Stock-airbox parts and clamp-on filter options represent different setups, while a carburetor service kit addresses one carburetor rather than the complete four-carb bank.

Choose the kit quantity for the work planned

One rebuild kit services one CB500K carburetor. Its stated contents include gaskets, needle-and-seat parts, jets, a jet needle and small hardware; four kits are required for the complete rack. A new float is a separate listing, so do not assume every worn carburetor component is included.

Retain the distinction between stock and custom intake

The stock-type filter is selected for an intact compatible airbox. Clamp-on filters require a confirmed inlet diameter and appropriate rack support. Check the airbox boots and engine-side holders separately; the four-piece sets are different parts and use different clamp specifications.

Common questions

What comes in a carb kit, and what needs ordering separately?

One kit contains bowl and top gaskets, a 1.8 needle-and-seat, jets, D26 jet needle, O-rings, screw with spring and C-clip. It services one carburetor. Floats and engine-side holders are not named contents; four kits cover the complete rack.

Which intake rubber and clamps suit the joint I am repairing?

The engine-side holder set supplies four holders, referencing 16211-323-000, with eight separate 41–44 mm clamps required when needed. The airbox boot set supplies four boots using four 45–47 mm clamps. Identify the retained intake joint before choosing either package.

What comes with the chrome fuel cap rather than its separate latch?

The cap references 17510-323-310 and includes a gasket, hinge pin and E-clip. The latch assembly separately names a chrome latch, return spring, mounting pin and C-clip. Compare the retained latch so a cap order does not duplicate needed hardware.
