Frequently Asked Questions

How many carburetor rebuild kits are needed for the 1977-1978 CB550K?

One kit rebuilds one carburetor. The 1977-1978 CB550K has a four-carburetor rack, so four kits are required to rebuild it completely.

What parts are included in each carburetor rebuild kit?

Each single-carburetor kit contains float-bowl and carb-top gaskets, a float needle, #90 main jet, jet holder, D376 jet needle, adjusting screw and spring, E-clip and six O-rings.

What should be checked before installing the supplied jets and needles?

Compare every metering part and stamped jet size with the original carburetor and the Honda specification. After assembly, set float height and mixture adjustments correctly and synchronize all four carburetors.
