[Irish]

finally got the bike running but my brother said he broke this thing and doesnt remember where it goes and i can find it... any ideas??? its on the throttle side of the bike. seems to be pretty important cause my bike runs like ****. thanks in advance .org!

Isn't that the one that goes to the sensor under the airbox? (I could be completely wrong.)

i think your right. theres about 3 of them that go to the bottom of the air box and that looks like one of them

Any open vacuum line will make the bike run bad.
Have you removed the pair valve? Could go there.
Is there another vacuum hose that points to the front of the bike? If not then it may go to the flapper valve in the airbox.
Figure it out yet? Can you take a better picture of all the other hoses?

like pipefighter said, any open vacuum line will make the bike run bad.
heres a pic of the 2 vacuum lines connected to the bottom of the airbox. the top one goes to the IAC flapper, the bottom one goes to the IAP sensor.

they really arent on the throttle side, i couldn't see your pic.
hope this helps...

The hose I've coloured in red is the one he's talking about. Does that help at all?

That hose would normally go to the pair valve.
But without seeing the rest of the hoses or if the bike has been modded; then we can't tell for sure.
Might have been moved around.

The pair valve is a epa device, that is normally taken off whenever people start modding their bikes. The pair valve is located behind the header with tubes going up above where the headers tie into the engine, there will be a vacuum hose off the throttle bodies going to it, and then a hose going into the airbox from the pair valve.

You can go to a suzuki dealer website and look at the microfiche. It is under the 2nd air.
That it what it looks like with hoses and such.

Irish, I can see the picture now, this morning it was just a red "x". If your question hasnt been answered by the time I get home, Ill go through my pics and post a more helpful one.

I hope you get it figured out, I know you've been frustrated...

 

[Irish]

ok, here are some more pics... im still lost on this one. i hate this jolting around business, it is ridable but rough.

 

[Irish]

one more highlighting the questionable line. and again, sorry for the first picture, its really tedious to post pics from my cell phone but now im home and u can have all the pics u like

 

[Pipefighter248]

That line goes down to the pair valve located behind the headers.

 

[Irish]

ok cool thanks, now its time to figure out what im going to do with it since the little plastic nipple was broke off in the tube. rubber cement sounds good right about now, maybe silicone

 

[Pipefighter248]

Is bike completely stock?
Bolt ons? Full system?
You could always remove the pair valve.

Ok so i read through that forum and know what i must do! DEATH TO THE PAIR VALVE!! So i do have a full D&D exhaust and its been throwing 2 foot flames since i got it and i can see the pair valve. Took us breaking this vacuum line to diagnose the backfire FIRE issue hahaha. Thanks PipeFighter! and thanks again and again and again Denon, one thing i can count on, the .oRg got my back! Bought a bike that has problems and with no mechanical knowledge, I am slowly but surely ironing them out with ALL of You Guys' help!
