GS550 BS32 carburetor vent lines

[Qwerty130]

Hi guys, i have an 82 gs550 that i am throwing together and i am wondering where i am supposed to route the 2 vent lines between the outermost carbs and their middle counterparts? I found some old post asking the same thing with a comment from nessism (thanks for the reseal kit if ur reading this, glad i didnt have to fuss with the sizes all by myself) linking a site called "bikercliffs" but all the pictures under the referenced fuel hose sections arent being hosted anymore (I HATE PHOTOBUCKET). I also looked at his rebuild tutorial but i didnt find that helpful for the vent hoses (maybe its just me idk),, thanks in advance.

The vent hoses route up and back, to some secure place above the airbox. Keep the hoses open, so the carbs can "vent".

I run mine over the airbox and through the little metal strap on the back right side of the airbox. Left side vent hose is a little longer to make it over there (over the top of airbox first then across above the "snorkel"). They both terminate right at the bottom edge of the airbox.

I will add that I also used to route mine over and behind the airbox, which I believe is the correct routing. However... In certain circumstances, high crosswinds, at highway speeds, can blow right into the space under the carbs and get "scooped" up behind the airbox. Because the vent tubes terminate exactly there, it can cause changes in air pressure inside the carb bowls causing temporary a temporary lean condition. (Hesitation and loss of power).

This is kind of rare, but it does happen. I've had it happen twice. Not a huge deal but it can be disconcerting at first. Chaning direction or speed can resolve it immediately, or if the crosswinds slow down.

What I did to solve this is route the lines up and under the seat. They still vent to atmosphere and maintain normal pressure in the bowls, but are no longer affected by turbulent crosswinds. You don't have to do this, but its helpful to know in case you use the standard routing and encounter this condition.
