I've been searching for an hour, I must be using the wrong words...! Please help me find the size of the O-rings that seal the fuel pipes between the carbs on a '77 CB550. PD 46A carbs. CMSNL calls it a joint set ( #1 in the parts fiche that I can't figure out how to copy here). I can take pictures if needed, but that is another 1/2 hour of fumbling with camera and 'puter.
Thanks
