Inspect the complete intake system

For a 1972 CB500K intake repair, stock air filter 15-0162, engine-side holder set 48-1476 and airbox boot set 73-0137 are separate catalog items. The two rubber sets each contain four pieces but serve different connections. Inspect the original airbox and both sides of the carburetors when planning the work.

Fitment questions

Does the rebuild kit include the carburetor float itself? Kit 73-0829 lists a float needle and seat, but not a float body. Float 20-6511 is a separate CB500K listing supplied with a pin. Distinguish a worn inlet valve from a damaged float before deciding which parts the repair needs.

Can a CB550 clutch cable replace the listed CB500K cable? Cable 73-0191 names the 1971–73 CB500K and reference 22870-323-020. Cable 73-0195 names CB550K/F applications and a different reference. These listings do not establish a cross-substitution; compare the fitted control ends and routing if the handlebars or controls have changed.
