What are these tubes? Where do they go?

Postby qonfusion » Fri Aug 12, 2016 3:59 pm

Hi all,

I continue to battle with my 1979 CB650.

Two tubes coming off the carb rack currently go nowhere. On this diagram (see link), they are part number 16. (http://images.cmsnl.com/img/partslists/ ... 8_7fec.gif)

Does anyone know where and to what these are supposed to connect? When the bike runs, if I pinch them it seems to run A LOT better.

Any thoughts appreciated.

Right, but they go no there directly but join in a tee (#20 in the CV carb drawing below). From there a single hose goes to the airbox so you won't find two connectors! In this post is an ebay link that shows the missing tube and tee connected to the airbox.
