1980 Honda CB650 Parts

Parts and fitment guide for your 1980 CB650

This collection brings together listed repair and maintenance parts for the 1980 Honda CB650 Standard. Confirm the exact model and fitted component; a shared CB650 name does not make every Standard, Custom and Nighthawk part interchangeable.

Choose the 1980 carburetor kit

Carb kit 48-1662 specifically lists the 1980 CB650 and includes #90 and #95 main jets and a #59A slide needle. Those numbers describe the replacement kit, not an instruction to change the fitted jetting. Compare the carburetor identity and required specification before choosing which supplied parts to use.

Fitment questions

Can the 1979 or 1981–82 holder set be ordered for a 1980 bike? Neither listing establishes that application: holder set 73-0133 lists 1979, while 73-0134 lists 1981–82 CB650. Identify the fitted holders and get confirmation for 1980 rather than filling the gap with the nearest year.

Which float listing covers the 1980 CB650 carburetors? Float-with-pin 20-6509 lists the 1979–80 CB650. Float 20-6507 instead lists the 1981–82 CB650. Compare the installed carburetors and old float before ordering, particularly if a later carburetor assembly has been fitted.
