Part of 1978 R100/7 Side Car
Bing Carb Rebuild! These were the first carbs I have ever rebuilt and were absolutely delightful to work on. They were pretty clean overall but the O-rings were hard and disintegrating, diaphragm was ok but showing its age along with a few other easy parts to replace.
Parts sourced from https://www.bingcarburetor.com/. O-rings for jets, pilot, air screw, and choke. Diaphragms and jet needles for slides. Floats, seats and needles, and gaskets for bowls.
