Curious to this one too, but from my experience with my own VX, here's what I BELIEVE to be the answer:

The VX runs better on the "top side" of the tank, I've noticed. Like, RIDICULOUSLY better. Prior to putting it in the garage port, I had just (finally) really began to discover and experiment with this.

For instance, I could run about 450 miles (tops) with my current driving tech/mods/routes on the full 8 gallon tank, netting around 55mpg or so. BUT, if I just ran 4 gallons worth of full and filled up, I was easily toping 60mpg.

Only run one gallon? Expect close to 70mpg! NO mods to tech, just running on the higher side of the tank, I believe, increases fuel pressure from the (always sorry) OEM Honda fuel pump, and I believe leads to more efficient fuel atomization.

Donkey, can you confirm my logic here?

Thanks for the underside pics! SICK set up !!!!
