1981 Honda CB900F Supersport · Gaskets & Seals Buying guide
A valve-cover repair, cylinder removal and a shaft leak require different sealing parts on the CB900F. Identify where the oil starts, then compare that joint with the gasket package contents before ordering.

The Athena top-end package names the head, cylinder base and valve-cover gaskets, four exhaust headpipe gaskets, the camshaft-holder seal, four sleeve O-rings and various O-rings. It is a defined package for top-end work, not an automatic substitute for every lower-engine gasket.
A new gasket cannot repair a distorted cover or damaged mating face. Clean away old material without gouging the aluminum, retain the correct dowels and follow the Honda tightening sequence. Use sealant only where the service procedure calls for it.
No. Check the mating faces, cover condition and fastener lengths, and confirm that oil is not running down from another joint. On the CB900F, a nearby shaft seal or head-cover seal may require a different part.
The Athena top-end package lists its head-and-cylinder gaskets and associated O-rings, not a complete set of shaft seals. The separate oil-seal kit covers six named shaft locations. Check the actual leaking position and package list rather than assuming one set covers both jobs.
Use the Honda instructions for the joint being opened. The separate valve-cover gasket references 12391-425-010; inspect its sealing surfaces and the nearby cover seals rather than coating the whole gasket to mask an unresolved leak.
