Topic: Carb question about size

[jamesb]

Are the 77 f model carbs bigger than the regular carbs on a 74 cb750. I can get this real cool chopper breather but the carb boots are larger so I would have to make a plate or something so my 74 carbs will fit properly. This breather is unique I have never seen anything like it and I got to have it.

Both bikes use 28mm carbs. Although the intake ports are 31mm on the F1-F2, I think the air-cleaner tubes are the same diameter.
