Pièces Honda CB650 1981

Parts and fitment guide for your 1981 CB650

This collection brings together listed repair and maintenance parts for the 1981 Honda CB650 Standard. Confirm the exact model and fitted component; a shared CB650 name does not make every Standard, Custom and Nighthawk part interchangeable.

Confirm the CV-carburetor application

Kit 48-1977 lists 1981–82 CB650 with CV carburetors. Compared with it, Deluxe kit 48-1992 additionally lists a needle jet and jet needle. The smaller 48-1402 kit lists a bowl gasket, float needle and O-rings. Choose by the worn components and stated contents; the word rebuild does not mean all three kits supply the same parts.

Fitment questions

Will the band clamps listed for the 1979 holder set suit the 1981 replacement set? The listings specify different band-clamp ranges: set 73-0133 calls for 46–49mm clamps, while the 1981–82 set 73-0134 calls for 50–52mm clamps 15-0689. Select clamps for the replacement holders you are buying rather than carrying the earlier set specification over.

Does a leaking fuel-connector tube call for the same seals as a bowl repair? Tube O-ring set 73-0831 is a separate 12-ring listing for fuel-connector and accelerator tubes, with 1981–82 CB650 coverage. The bowl-rebuild kit descriptions do not establish that this tube-seal set is included. Identify where the leak occurs before choosing the seal order.
