Needle jet holder, also known as an emulsion tube, for the Honda CB550K from 1977-1978. These are no longer available from Honda. This is the long tube that fits around the needle jet, as the slide rises and lifts the needle, more holes on the emulsion tube are exposed, thus more fuel is available for atomization. If those holes are plugged, or if the tube has been damaged, the engine won't run right above 1,200 rpm. It's listed in the parts fiche as part of the "Needle Jet Holder."
