Have anyone modified viper stock air intake to make it work like ram air system should work? (stagnation pressure?)

I was thinking that i can use some plastic pipe to control air flow straight to air box? Route marked on pic with amazing paint skills.
 

You won't have enough speed to make pressure or more hp. You may move enough air to trick the carbs into running lean going into a good head wind.
The sled MFG make the air box so it pulls neutral air. That way your jetting is constant.

Four stroke street bikes have room to lean out and not hurt anything, 2 strokes do not
