Description

Keep fuel flowing reliably to your carburetors with this Fuel Petcock, designed as a direct replacement for several original Honda fuel valve assemblies. This unit replaces OEM part numbers 16950-MA6-035, 16950-MA6-025, 16950-ME5-005, and 16950-ME5-015, helping restore proper fuel delivery and shutoff control.

Over time, petcocks can become clogged, leak, or fail internally, which can lead to fuel flow problems or difficulty shutting off the fuel supply. Replacing the petcock helps ensure consistent fuel delivery and dependable operation.

Frequently Asked Questions

How many fuel petcocks are included for the CB550SC or CB650SC?

One petcock replacing Honda OEM 16950-MA6-035 is included, enough for one compatible 1983 CB550SC or 1983-1985 CB650SC fuel tank.

What should be matched before installing the petcock?

Confirm OEM 16950-MA6-035, tank mounting or thread arrangement, outlet direction and fuel-hose size. Similar-looking Honda petcocks can use different connections.

What checks are required before riding?

Flush tank debris away from the valve, route the fuel hose without kinks and test every valve position. Fill the tank only after the seal is secure, then inspect for leaks with the engine running and stopped.
