Pièces Honda CB900C 1980

Parts and fitment guide for your 1980 CB900C

This 1980 Honda CB900C Custom collection includes stock-airbox and paper oil-filter service parts. The linked 73-0139 airbox boot set lists the 1980–82 Custom, but shared intake fitment does not establish interchangeability for the motorcycle’s other assemblies.

Keep the two sides of the intake distinct

The selected 73-0139 boots connect the carburetors to the airbox. The set contains one each of four different replacement references, 17251-438-000 through 17254-438-000. Engine-side holders are different parts. For this airbox set, the listing specifies 60–65mm band clamps 15-0673 when replacement clamps are required.

Fitment questions

Can the CB900C carburetor be identified by model year alone? Honda’s manual distinguishes VB43A and Canadian VB43B carburetors and places their identification on the carburetor body. Check that marking and the original market before selecting metering parts for a 1980 Custom.

Does the oil-filter element replace the housing spring and seals? No. Paper element 15-0002 lists O-rings, springs and washers separately. Compare what is present in the filter housing before ordering so a missing service part is not mistaken for something supplied with the element.
