Routing carb vent

The last time I pulled my carbs I left a very long tube after the T so I could place the vent wherever its suppose to go. It turns out its not so obvious where it goes. Also, if you put it in the wrong place it really affects the bike. So for now I've shoved it under the seat, unable to find the correct location behind the air intake, but even under the seat I'll get some slight starvation around 50mph. The other day I had it shoved behind the air intake and the bike was really bogging down. I pulled the hose out and held it and the bike leap forward! It amazing what a difference it makes, whether its parallel with the air, or air directly in it, etc!

So precisely, where am I suppose to place this tube?

I'm earshaved and put my vent under the gas tank, ziptied to the frame.

On stock ears, it goes in the right ear, one of the holes on the back end. Here's a pic and a thread:

If you have a square small box with a connection under the fuel tank, just where the fuel gage is. That can also be used for that hose.

People who carry on about how great their bike runs sometimes will not realize their losing.

The vent must end in 'dead air', to function properly. Intake air must enter a CV carb virtually straight for optimum performance. There is no way I know to tune around these facts.

I've got my line running under the tank not hooked to anything. I'll get an occasional hiccup when driving into the wind. Thought about hooking it to fuel sender cover, but didn't.

I only understand what I don't understand.

I was mainly poking fun at myself, wm, for carrying on, so much, everywhere, about how great my bike is running. But I did think you were talking about my posts. I'm kinda confused by the last line... But I am often confused so it's a familiar feeling at least. lol

First time I have ever typed that. They get confused when I don't type it. Let the record show they get confused when I do.






LOL.
