1982 Honda CB900C Custom · Tank Caps & Petcocks Buying guide

Identify the 1982 petcock, strainer and automatic shutoff separately

The tank petcock, its strainer cup and the separate automatic fuel shutoff have different service needs. The featured petcock is M20 × 1.0; the repair kit is listed for the 1982 automatic valve. Inspect the actual assembly before choosing either.

Inspect the 1982 strainer before replacing the whole valve

Honda’s 1982 addendum shows a removable strainer cup with a screen and O-ring. Inspect the source of a leak or restriction and compare the tank’s actual M20 × 1.0 fitting. A changed tank or valve can alter the parts required; the automatic shutoff repair kit does not rebuild the manual petcock.

Match repair-kit pieces to the installed automatic valve

The kit listing warns that one supplied O-ring may not be used in every supported version. Compare the original valve and the applicable instructions rather than fitting every spare seal. Check the fuel, vacuum and vent connections and verify correct operation and no leakage before use.

Tank Caps & Petcocks questions

Can a blocked tank vent look like a carburetor fault?

Yes. Honda includes a blocked fuel-cap vent among causes of a lean mixture or restricted fuel supply. Check venting, the strainer and fuel line before buying jets or a carburetor kit.

Does the automatic shutoff kit also repair the manual tank petcock?

No. It services the separate automatic valve. The manual petcock and its strainer have their own seals and service procedure. Identify where the fault starts before ordering either a replacement petcock or the repair kit.

Must every O-ring in the shutoff kit be installed?

No. The source explicitly notes that one may not be used in some applications. Match the fitted valve construction and repair instructions, then check operation and leakage; an unused alternative seal is not a reason to force it into another location.
