1981 Honda CB900F Supersport · Engine Buying guide
The CB900F uses a 902cc air-cooled, four-cylinder engine with chain-driven double overhead camshafts and sixteen valves. Oil-filter service, shim adjustment and cylinder rebuilding expose different parts; choose the repair scope before choosing a package.

A top-end strip exposes more sealing joints than a valve-cover repair. The Athena top-end set lists head, base and valve-cover gaskets, the camshaft-holder seal, four sleeve O-rings and four headpipe gaskets. Check that list against the work actually planned before adding separate duplicates.
Valve clearance is checked with the engine cold and corrected with measured replacement shims. A piston or ring order needs cylinder measurements instead. Cam-drive noise also calls for inspection of the chains, guides and tensioners; it does not identify one failed part on its own.
No. Each kit serves one piston, but standard size is suitable only after the bore and piston clearances have been assessed. A worn, tapered or previously rebored cylinder may need a different machining and parts plan.
Check the housing and bolt O-rings, filter spring and washer as well as the paper element. The element does not include those pieces. A missing or damaged housing part needs attention before the engine is returned to service.
List the joints being opened. The Athena top-end set names head, base and valve-cover gaskets with associated seals; the overhaul set adds named lower-cover gaskets and sixteen valve-stem seals. Match the contents to the job, and check shaft seals separately.
