1979 Honda CB125S · Carburetor Service Parts Buying guide

Distinguish the fuel-control part from the drain fitting

The needle replaces 16011-382-004; the drain screw is a separate sold-each product with an O-ring. Match each part to the fitted carburetor rather than treating them as a rebuild kit.

Establish the affected part before choosing the order

A float needle and bowl drain screw serve different locations. Inspect the fitted carburetor and identify the source of the problem before selecting either. Use the correct service information for diagnosis; ordering both parts is not a substitute for finding the repair point.

Make a separate list of retained components

The float needle product is expressly needle only. The drain screw is supplied individually with an O-ring. Inspect the surrounding seat and bowl connection separately, then identify any additional parts needed rather than assuming those two purchases complete a carburetor rebuild.

Buying questions

Does the float needle include a replacement seat?

No. It is specified as the float needle only, replacing 16011-382-004. Inspect the retained seat separately and resolve any additional repair need before assuming a needle-only order covers it.

Do I need an O-ring for the pictured drain screw?

The O-ring is included with that drain screw. Compare the existing screw and bowl connection before ordering; an included seal does not establish the condition of the bowl or its receiving thread.

Will these parts suit a replacement carburetor?

Identify that carburetor first and compare the required needle and drain fitting. A replacement carburetor may use different components even when installed on the same 1979 motorcycle. Its own specification should guide the comparison.

Not sure which part you need?

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