1983 Honda CB550SC · Petcock & Tank Mounts Buying guide

Choose valve service and tank support separately

The petcock and its repair kit address the fuel valve, while the rubber cushion supports the tank. Compare references and contents for each job; a mounting-rubber order is not a fuel-valve package.

Identify the valve before choosing a kit

The petcock repair kit includes a diaphragm, spring and two O-rings. The complete replacement valve has a separate description and four OEM references. Compare the installed petcock and the work needed; neither choice should be assumed to include the tank mounting cushion.

Count cushions on the fitted tank arrangement

The aftermarket cushion replaces OEM 17611-KE8-000 and is sold each. Its general quantity note says most applications use two, rather than giving a CB550SC-specific count. Check the mounting rubbers actually fitted, especially where the tank or its supports have been modified.

Petcock & Tank Mounts questions

What does the repair kit supply?

Its stated contents are a diaphragm, spring and two O-rings. The application includes the 1983 CB550SC; compare your fitted valve before choosing these service parts rather than the separate replacement petcock.

Is the selected mounting rubber a genuine Honda item?

The selected cushion is described as an aftermarket replacement for OEM 17611-KE8-000. That reference identifies the application; it does not change the product into a genuine Honda part.

Does one cushion purchase provide a pair?

No. The cushion is expressly sold individually. The description gives a general most-applications quantity note, so count the supports needing replacement on your motorcycle rather than assuming a pair is supplied.

Not sure which part you need?

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