This is a complete step-by-step procedure for rebuilding and restoring a set of HONDA CB550 carburetors that is provided via the link below. It reflects my personal experience with rebuilding a few sets of 022A carburetors (used on 1974-1975 CB550K), 087A (used on 1976 CB550K) and 069A (used on 1975-1977 CB550F). It can be used by those who need to perform only regular maintenance as well as those who want to do a complete rebuild. Regardless of the extent of the job, the use of aftermarket components should be avoided, if at all possible. Many aftermarket kits are available and inevitably there is the assumption that all parts are as good as the OEM and the temptation to “save a few buck” is almost irresistible. My advice is: don’t do it. Many of the parts won’t fit (for example, the O-ring for the fuel bowl is normally much smaller that the original and made of a material that is not compatible with fuels; the float valve is sightly larger than the OEM and very difficult to fit, the float valve needle can be the wrong size and the wrong design, etc., etc.).

NOTE: The carburetors pictured in the photo above and in the step-by-step procedure are identical to the ones mounted on the bike as pictured elsewhere on the website. I rebuilt them for the fun of it and because I wanted to have a spare set.QUESTIONS?
