1982 Honda CB900F Supersport · Tank & Shut-Off Parts Buying guide
The petcock references 16950-MA4-771, while the repair kit services the automatic shut-off assembly. Front tank cushions and a cap seal should be assessed separately rather than included in an assumed complete tank-repair package.

The listed 1982 petcock uses M20 x 1.0 threads. Honda’s 1982 supplement also shows a fuel-strainer cup, screen and O-ring as distinct service pieces. Inspect the fitted valve construction; the automatic shut-off kit is not a substitute for those tank-valve parts.
Check the front cushions, tank mounting channels and rear support while access is available. A cap seal cannot correct a bent sealing rim, damaged latch or rusty tank neck. Confirm that the cap vents as designed, and leak-test any fuel-system repair safely before riding.
No. Measure the actual connection and compare its sealing arrangement, outlet direction, hose size and lever clearance. The 1981 listing specifies M18 x 1.0; the 1982 listing specifies M20 x 1.0. Neither year proves the thread on a replacement tank.
Inspect the cap rim, hinge, latch and tank neck for damage or corrosion as well as the rubber. Confirm that the cap vents correctly. A seal-only part cannot correct a distorted cap or sealing surface.
No. It repairs the separate automatic shut-off assembly. Match its construction and hoses before ordering; one included O-ring may be unused. Inspect the tank valve’s screen, cup and seal separately where that original arrangement remains fitted.
