1970 Honda CB100K0 · Fuel System Buying guide

Choose parts for the repair location

A tank-to-petcock seal, carburetor float and bowl drain screw address different parts of the fuel system. Identify the fitted hardware first, then use the stated application and contents to shape your order.

Keep the tank seal tied to the petcock

The body seal sits between the fuel petcock and tank and is specified for a stock OEM petcock. The separately offered replacement petcock has a longer body and a differently positioned outlet on some models. Do not transfer the stock seal application to that replacement by assumption.

Order carburetor parts by their supplied contents

The float is supplied with a pin, and the stock-type drain screw is supplied with an O-ring. Both are sold each. Compare the fitted carburetor before ordering, then use the service manual for inspection and setup rather than treating replacement parts as a diagnosis.

Buying questions

Can I use the stock seal on a replacement petcock?

Only choose this seal after confirming a stock OEM petcock. An aftermarket replacement can have a different sealing arrangement, even when the complete petcock is offered for the same motorcycle.

What is included with the float and drain screw?

The float comes with a pin; the drain screw comes with an O-ring. Each product is sold individually, so select the required quantity for the repair rather than assuming a multi-part set.

Will these carburetor parts fit a swapped carburetor?

The float and drain screw include the 1970–72 CB100K in their application. A swapped carburetor needs a separate identification check before that motorcycle-level application can be used to choose its internals.

Not sure which part you need?

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