1965 Honda CB72 · Fuel System Buying guide

Build the parts order around the diagnosed repair

The supported replacement here is a bowl-drain screw. Keep the repair scope clear, record the carburetors fitted to the motorcycle and select other fuel-system components against their own application information.

Parts to consider

Honda CB Stock Type Float Bowl Drain Screw Bowl-drain screw with O-ringStock-type drain screw, sold individually with its O-ring. The specified CB72 1961–66 application includes 1965.View part

Separate the package quantity from the repair quantity

One purchased unit supplies one screw with an O-ring. Order for the drain positions that require replacement, rather than assuming the product is a complete-motorcycle pack. A total installed quantity is not specified; establish the actual scope of the repair before choosing how many to buy.

Identify changed assemblies before ordering

A motorcycle can retain its model identity while carrying replacement carburetors or bowls. Keep any markings and known replacement history with the parts enquiry. The screw’s CB72 range supports the named application, but cannot identify a different assembly fitted during previous work.

Planning a fuel-system order

What should I order if only one bowl-drain position needs repair?

The screw is sold individually, so the order can follow the confirmed repair scope. One unit includes its O-ring. Check any other diagnosed faults separately instead of assuming this purchase covers every fuel-system repair.

How does a carburetor swap affect this parts choice?

Use the replacement carburetor and bowl identification to establish the required screw. The stated CB72 1961–66 application includes 1965, but it does not establish compatibility with an aftermarket or different-model assembly.

Should a fuel leak near the bowl mean ordering this screw?

Have the leak source identified before buying. Its location near a bowl does not identify the failed component. Choose this screw when the diagnosis calls for its replacement, and check any additional parts against their own application details.

Not sure which part you need?

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