Vacuum line size Help

Hey guys, my 2006 Suzuki GZ250 is running fine in prime, but then when in the on position it stalls... So I read the forum, check, took a look and it will prolly be the vacuum line. I would appreciate if someone has some ideas. does the bike have to have two rubber hoses from the pet cock? or just one?
Thanks for the help.... Great forum

Thanks Blaine, So basically where I show in the pic is what my nice bike is missing? Do you know the size for the vacuum hose line? Thanks again.

Should be a nipple on the petcock that the vacuum hose from the carb goes to.I don't remember what size it is.

That one is a float bowel drain hose.It just lies down over the back of the engine so if the carb floods the excess fuel flows onto the ground & not on the engine.

You should be able to feel it sucking air with the bike running.If it's open & sucking air the bike will run like crap.

Re: Vacuum line size Help

Here is a picture of the shut off switch showing both niples. The small niple is the vacuum line.

Re: Vacuum line size Help

Hello, Mole2, thanks very much for the pictures.. they help a lot. So I check and it is definitely missing the vacuum hose, the small niple has nothing attached to it. I bought a 7/32'' ( 5.5mm) and it fits perfect in the small nipple... I also bought a 9/32'' (7.0 mm) as I was not sure, Now, where do I have to attach the other end? . I read the service manual, and could not find anything about the vacuum hose. Thanks again for the information...
