1983 Honda CB650SC Nighthawk Petcocks & Tank Mounts

A fuel leak and a loose tank call for different parts on the 1983 CB650SC. Compare a complete petcock with the repair kit when the valve needs attention. Front tank cushions support the tank itself and are sold individually, so inspect both mounting points.

1983 Honda CB650SC Nighthawk · Petcocks & Tank Mounts Buying guide

Identify the fitted valve before choosing a repair

Choose the valve work and the tank-mount work separately. The repair kit and replacement petcock both list this Nighthawk, but shared motorcycle coverage does not establish that the kit rebuilds the replacement valve.

Use the kit inventory to check the repair scope

The kit lists a diaphragm, spring and two O-rings. Compare that inventory with the parts needed for the identified valve before ordering. Confirm any other essential component rather than assuming the listed inventory covers every repair.

Compare replacement references with the fitted valve

The replacement petcock lists Honda references 16950-MA6-035, 16950-MA6-025, 16950-ME5-005 and 16950-ME5-015. The listing supplies one valve; the separate repair kit has its own application.

Petcocks & Tank Mounts questions

Will this repair kit rebuild a previously replaced petcock?

Confirm the existing valve identity first. Kit 20-0020 and the listed replacement petcock both list the CB650SC, but their product records do not establish that they fit each other or that the kit fits an unidentified aftermarket valve.

What tank-connection measurement do I need before buying the valve?

Compare the fitted tank mounting or thread arrangement, outlet direction and fuel-hose size. The replacement listing does not state a thread size or connection dimensions, so obtain those details before ordering for a changed or unidentified tank.

When is a diaphragm-and-seal kit insufficient for the petcock repair?

Inspect the valve body and sealing faces for corrosion, pitting or cracks and clean its passages. The diaphragm, spring and two O-rings cannot repair a damaged body; choose the repair only after identifying the valve and assessing those surfaces.

Not sure which part you need?

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