1982 CB650SC carb cleaning

Postby Hutch1 » Sun Jul 16, 2017 8:45 pm

I noticed when cleaning the carbs there are tubes between carbs 1 & 2, and 3 & 4 visible from the choke plate side that have holes in the middle (see pics). I can't figure out what this tubes/parts are on the part diagram, can anyone shed some light? Is this normal or do these have to be replaced?

Those tubes are vents. Where you see the holes should actually be T fittings with a hoses coming off of them. Those hoses go over the top of the airbox. They do not connect to anything. You should replace them, as the carbs may leak if you do not.

Does anyone know the part number, it was difficult to tell from the diagram. I think it might be 16031469004 fuel joint set.

That's just one of the the small aluminum fuel pipe that connects the carb banks. What you want is this:

Seems pricey for what should be a $3 part, but at least they are available.
