Does anyone know off hand which model Keihin carb came on the 1975 CB550? I'm thinking I have to rejet my carbs, and I've found jetting kits that come with an assortment. Obviously based on some awesome advise from you all, not a permanent solution as name brand jets will be used once the proper jetting size is found, but I think I need the model of the carbs to ensure compatability for the jet kits. Thanks
