1978 Honda CB125S5 · Carb Rebuild Parts Buying guide

Use the needle reference to define the repair order

This needle-only replacement has an explicit 1978–82 CB125S application. Compare reference 16011-382-004 with your carburetor parts information, then identify any other components needed before treating the order as complete.

Compare needle-only and kit contents

The featured purchase is the float needle only. That precise scope matters when comparing it with a kit or a needle-and-seat assembly offered elsewhere. Use reference 16011-382-004 to check the component rather than assuming similarly named carburetor products contain the same parts.

Keep adjustment decisions separate

A replacement needle reference does not specify a jet size or a carburetor adjustment. Identify those needs from the carburetor being serviced and the correct service information. If the carburetor has changed, confirm its identity before using this motorcycle application to order.

Common ordering questions

Can this replace a complete needle-and-seat kit in my order?

It covers the needle only. If your planned repair calls for a seat as well, confirm that component separately; do not assume the contents match a complete needle-and-seat package because the names are similar.

Which identifier should I use when comparing rebuild-kit contents?

Compare the needle against replacement reference 16011-382-004. It identifies the featured component more precisely than a general rebuild-kit description, but you still need to check the rest of a kit’s contents separately.

Will the stated application cover a non-original carburetor?

Identify the fitted carburetor and its required needle before ordering. The supported CB125S application is 1978–82; a changed carburetor needs its own component match rather than relying only on the motorcycle year.

Not sure which part you need?

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