Title: carb vent hoses help
Post by: Nocluejoe on May 14, 2014, 02:52:51 PM
Re jetted and installed kn pods need help with hoses. The two Ts on the carbs the upper one gets a foam breather. What does the lower T get hooked up to and where does it go?

I have a line coming from the plug in sensor that has a line that goes to left side of carb then it continues and has a T on it and enough hose to reach the petcock is that where it goes? If not where to?

Missing a vaccum line on the petcock where does this line go to?

2 lines coming from engine that went to air box should I just plug some kind of filters to the ends? There is two of them

Ok figured out the left side vaccum hoses that went to petcock  I think just need to figure out what to do with hoses that went tk air box and what this lower T on the carb gets hooked up to the one right under neath the throttle cable

The lower 'T' is your fuel line from frame petcock. 

Upper 'T' is the carb vent - This you want to have the end of this vent out of any wind.  If enough air flow hits the end of that tube, it will create pressure which doesn't allow the fuel to flow properly into the carbs = fuel starvation symptoms.

Pics always help.  So just for clarification...

Quote from an adidasguy post awhile back:
"The  YELLOW oval is the brown T where there is the single fuel connection from the frame petcock.
The GREEN circle is a vent hose - connects to nothing"

That vent hose routes back near the battery box - tuck it away so no wind can catch the end of it, and make sure you don't have any kinks or pinches.

Im attempting to upload pics says to large, but yes the green one is what I'm stuck on.

The bike wont idle it dies right away does the hoses from thr old air vent need to be sealed or a filter on it to run?  When it dies kind of puts out a white smoke

Does you bike have the PAIR system equipped? If so I'll dig up the diagrams and threads I just used to straighten mine out.

I don't think mine has the pair system I seen diagrams and they didn't match up with mine

I put one washer on the needle and it won't idle unless I'm giving a tad throttle then it will "run" fine as soon as I stop the throttle it backfires loudly and cuts off. Should I add another washer? Anything I can do? My idle screw is all the way in


I have a 2007 jetting is 147.5 60 20  k n pods and delkevic slip on

This hose seems to suck in a lot of air if I block it the sound of the engine changes where does this go?

Looks like you are an unlucky duck and got the shitty PAIR system. That device is one of the valves for the system. The hose end that is circled in red should be attached to the bottom of the airbox.

I removed the whole pair system off my 06 gsF. Look over the diagrams and previous threads on the subject, let me know if you have any additional questions
