1982 Honda CB900F Supersport · Cam Drive Parts Buying guide
The CB900F cam drive has separate A and B chain listings, guides and tensioners. Diagnose the source of noise before ordering: a new spring or tensioner cannot correct every worn chain, damaged guide or timing fault.

The linked main tensioner is described as genuine Honda and carries 14500-425-020, -010 and -000 references. The featured smaller B tensioner uses a different reference family. Keep that position distinction rather than transferring the genuine-manufacture description across all tensioner products.
The featured chains are specified as 412H. The separate 82RH2015 rivet-link listing expressly excludes 412H compatibility. Do not combine them merely because both appear among cam-drive parts; any joining link and installation method must be approved for the exact chain.
No. Inspect chain wear, guide surfaces and tensioner movement and confirm cam timing. The CB900F manual specifies cold-engine cam-chain tension adjustment; use its complete procedure rather than treating noise as proof that one tensioner has failed.
No. Its listing specifically excludes 412H. Both chain series and construction must match the joining link approved by the chain manufacturer. A shared category or similar-looking silent chain is not evidence of compatibility.
Match the removed component and Honda diagram. The larger main unit uses 14500-series references and spring A; the smaller B unit uses 14530-series references and spring B, 14538-425-000. Keep those assemblies and their springs separate.
