I was tooling around on Ebay looking at parts and came across a set of velocity stacks off a parted out bike.
What caught my eye is that I could see a lip midway down the throat. This is confirmed in the picture of the reverse side where you can see the notch cutaway gets thicker towards the middle.
So I bought them...and confirmed- yes, they do neck down in the center. ><

Soooo...I did a little work on them. Hard to see from the pictures, but it is much better now. Here is comparison to a stocker.
