Inspect the whole intake system

For the 1975 CB550K, holder set 48-1476 and airbox boot set 73-0137 each supply four rubbers for different sides of the carburetors. Their band-clamp requirements differ: 41–44mm for the holders and 45–47mm for the boots. Inspect both connections before building the intake-parts order.

Fitment questions

Can I order the 36-piece CB550F carb bolt kit for this K model? Kit 73-1045 names the CB550F, not the CB550K. Screw kit 49-0773 does explicitly list the 1974–76 CB550K, but does not itemise its screw count or sizes. Confirm the hardware needed for the fitted carburetors rather than transferring the F-kit contents to the K listing.

What support part is listed if the original airbox has been removed? Stabilizer bracket 29-0540 lists the 1971–73 CB500K and 1974–76 CB550K for pod-filter or no-airbox arrangements. That application does not establish clearance with every custom intake. Compare the fitted carburetor bank, mounting arrangement and surrounding parts before choosing the bracket.
