1982 Honda CB125S · Fuel System Buying guide

Identify the carburetor before assembling the order

The float needle replaces reference 16011-382-004. Treat it as one component of the repair and keep a record of any other worn pieces, especially if the carburetor has been replaced during earlier work.

Parts to consider

Honda CB Float Needle ~ Replaces 16011-382-004 Carburetor float needleNeedle-only replacement for reference 16011-382-004, with an explicit 1978–82 CB125S application.View part

Start with the source of the fault

Have the fuel-system fault identified before selecting a replacement. The float needle is a specific service item, and an overflowing or poorly running carburetor does not by itself establish which part has failed. Keep the inspection findings with your parts list.

Check a changed carburetor on its own merits

The needle has an explicit 1978–82 CB125S application. That application describes the listed replacement, not every carburetor that may have been installed since. For a replacement carburetor, compare its identity, the old needle and the required replacement reference before ordering.

Buying questions

What should I record if the carburetor has been changed?

Record its identifying markings and retain the old needle for comparison. The motorcycle year alone does not identify an aftermarket or transplanted carburetor, so establish that assembly’s replacement requirement before buying.

Is this a complete carburetor rebuild kit?

This is a float needle only. Build the rest of the order from the inspection findings rather than assuming the needle purchase supplies the other parts needed for a full carburetor overhaul.

Should fuel overflow be treated as proof that the needle needs replacement?

Have the cause assessed before ordering. Overflow is a symptom, and replacing one component without checking the fitted assembly may leave the fault unresolved. Use the diagnosis to determine the parts required.

Not sure which part you need?

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