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 :)

Two.The bigger one is fuel,the smaller on is the vacuum hose. :) :cool:

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.

Hey Blain, I found the hose, it is loose... please tell me it that is the right one... thanks, and where is supposed to be.. thanks again

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.

I can't seem to find which one is the vacuum line.. :(

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.

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

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... :) ;)
