Each carb is marked 751A. No guarantee of brand new performance, but I have never had a carburetor pair I have cleaned that came back.
Here's what you get. They both were completely disassembled and given 60 minutes in my ultrasonic cleaner. All passages blown out with air pressure. Reassembled with original parts.Fits 1970-1974 CB450 CL450 also 1975-1976 Honda CB500T
