Carb 'T' connections

[Guest]

I tore into the carbs off a newly acquirted '83 Katana 750 and noticed that there are three tee connections, one being for the fuel line. The two others did not have anything connected to them. The vacuum line from the petcock was properly connected too

I seem to recall that gas tanks that had a fuel guage sender needed to be hooked to one of the tee connections but this model has no such guage.

Shouldn't the two open tee connections be connected to something and if not, should they be plugged?

They should be vents for the carbs and left open. Usually there are rubber hoses that just lead to the back of the bike. At least that's how it works on bikes with CV carbs, not sure if that is what your bike has.

Hi,

Yes, they sound like vents. Usually they are connected to hoses that run over the back of the airbox. The hoses are often removed when pod filters are installed. Even if you plan on keeping your airbox, the vent hoses are not critical. Although you might notice some hesitation in high crosswinds.


Thank you for your indulgence,
