Motorcycle Repair: carbs, jet size, bill silver

Question
hi bill, are the carb slides interchangeable from cb77 carbs to ca77 carb. what size is the carb on a ca77? are the cb77 carbs 26mm? thanks for your help.

Answer
Charles, CB/CL77 carbs are interchangeable, other than the needle. Both are 26mm sizes. CA77 carbs, as well as CA72 carbs are 22mm sizes and the difference is the main jet size. There were round bowl and square bowl carb bodies and float chambers, however.

So, the answer is no, the CA77 and CB77 carb slides do not interchange. The CB/CL72 carbs are 22mm, but the slide cutaways are different than the CA77 versions.
