1981 Honda CB125S · Fuel System Buying guide

Start with the carburetor and the repair scope

A focused parts order begins with identifying the fitted carburetor. This float needle carries replacement reference 16011-382-004 and an explicit CB125S application covering 1981, giving you two useful checks before purchase.

Parts to consider

Honda CB Float Needle ~ Replaces 16011-382-004 Carburetor float needleFloat needle only, replacing reference 16011-382-004. The CB125S application includes 1981.View part

Define the order before buying

Keep the float needle on a component-by-component repair list. Its replacement reference identifies the item being purchased; it does not define everything needed for the job. Review the other worn or missing parts separately before completing the order.

Take a changed carburetor into account

The stated CB125S fitment includes 1978–82. If a previous owner fitted a different carburetor, identify that unit and compare its required needle with reference 16011-382-004. The motorcycle’s year alone is not enough to select parts for an exchanged carburetor.

Common buying questions

Does the float needle include a replacement seat?

No. This product is described as a float needle only. If your repair also needs a seat or other carburetor components, identify and source those items separately before placing the order.

Which replacement reference should I compare?

Use 16011-382-004 when checking the float needle. Compare that reference with the parts information for the carburetor actually fitted, especially when the motorcycle has an uncertain restoration or service history.

Is a different-year carburetor covered by the bike’s fitment?

Do not transfer the 1981 motorcycle application to an unidentified carburetor. The needle’s stated CB125S range is 1978–82, but a changed unit still needs its own component identification before you rely on that range.

Not sure which part you need?

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