Good question Rocco, I guess I don't know off hand but see where your coming from. What if you were to make it like and old school road draft tube? Hang in down at the bottom so as the air blows over it, it creates vacuum to pull it out. Maybe use a little piece of hard line at the end so it wouldn't whip in the wind. It would drip a little, you wouldn't be able to use the catch can to do it that way.

if you place the end where it open, the air getting across creates enough vacuum. the idea behind the re-route is not to create more hp, but to stop the exhaust fumes from being pushed back into the engine making less room for fresh, cool, usable air. this makes the burn process run more efficiently and creates more hp by itself, without running an additional vacuum pump. vacuum pump can be seen as 'the next step'...although nobody seems to have the need for it, since the gains would be minimum.

I originally did this mod to stop making a mess in the airbox. I wasn't expecting to see any improvements as far as the engine running better. The explanations were perfect. Got all the parts at Napa. They had everything on the list. After having done the mod, I went out for a ride to see that nothing was done wrong. I was truly impressed how much smoother the engine ran. What a difference. Thanks guys with coming up with this mod. I plan to take a look in my V-rod airbox to see if they did the same setup.

Ok so I decided to start the mod...I have to head to the store in a bit and i decided to take apart the bike first. I have everything off except the bottom of the airbox with the big horn in it. How do i get it off from here. The horn seem to be connected from below. The sensor is connected there as well. Some help here guys?

the bottom of the velocity stack (I am assuming that's what you are calling the "big horn") has two "gaskets" that are built as part of the velocity stack.  The base plate of the airbox is sandwhiched between the two gaskets and comes up and over the velocity stack.  Start pushing the gaskets through base plate, once you start one corner, it should start going pretty easy.  The sensor doesnt have to be disconnected, there was enough slack in the wires, I just carefully placed mine to the side.

BTW this mod has been done on evo sportsters a long time.Its a epa thing just to help meet ever tightening pollution specs dumping crank case gases back in the intake. It also causes the tops of your  pistons to carbon up faster when that crap is plumbed back in your air intake. So this is a great more in more ways than one.
