1980 Honda CB650 · Carb Kits & Metering Parts Buying guide

Choose a rebuild package or focused carburetor parts

The 1980 rebuild kit and separate press-in pilot jets address different parts of the carburetor. Identify the installed assembly and the required repair before combining the kit with individual service parts.

Check the remaining named kit components

The rebuild kit also lists a jet needle holder, nine various O-rings, a needle screw with O-ring, and a washer. Compare those components with the repair being planned.

Identify the individual repair parts by reference

The separate float needle replaces 16011-382-004, and the carburetor top gasket replaces 16014-393-004. Use these references when checking an individual-part repair against the carburetor actually fitted.

Ordering questions

Should I add separate gaskets and a float needle with the rebuild kit?

The kit explicitly includes the float-bowl gasket, carburetor top gasket and float needle. Compare those included parts with your repair list before adding separate replacements for the same carburetor.

How should I choose between number-35 and number-40 pilot jets?

Confirm the press-in jet type and required size for the actual carburetor and intake/exhaust setup. The two four-packs are alternatives for different requirements; the model listing alone does not select the correct size for a modified engine.

Does the separate float needle include a replacement seat?

That product is explicitly described as the float needle only. Identify any seat or other float-valve part needed for the repair separately rather than expecting it with the needle.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
