Plan your K0 carburetor rebuild

Carb kit 48-1907 lists the 1974–76 CB550K with a float needle and seat, main and pilot jets, needle, gaskets and O-rings. Its description gives no jet sizes. Compare the fitted metering parts with the correct service specification, particularly after intake or exhaust changes, rather than assigning sizes from a neighbouring-model kit.

Fitment questions

Does the separate float listing also identify a suitable setting gauge? Float 20-6511 and pre-set gauge 73-0888 both explicitly list the 1974–76 CB550K. The gauge description does not give a numeric height or setting procedure. Confirm the installed carburetors and use the correct service instructions before adjusting them.

Is the bronze swingarm-bushing set listed for the 1974 K0? Set 28-1026 starts its CB550K application at 1976, so its description does not establish 1974 fitment. Compare the fitted swingarm and pivot components and obtain confirmation for the K0 before choosing replacement bushings.
