Crossover = Useless
I was just outside having a smoke when a thought occurred to me. (Stand back).
It doesn't seem logical to me that having a crossover on our FI one-piece tanks makes much sense to me. It's one big tank, and to be honest I think the crossover just gets in the way and makes it a P.I.T.A. to remove the tank when doing major work to your bike that would require tank removal.
On the older two-piece tanks, yes , it makes sense.

My bike's not here at the moment, but are there two internal fuel pickups? The one-piece tank
straddles the upper frame tube so unless there are two pickups inside the tank, how would
you get all the fuel out of each lobe?

I think if you have a front tank lift installed you are correct, the crossover would not be needed. With a stock setup under a steady highway cruise when you get near the bottom of your fill the right side might not transfer the last half gallon or so without the transfer tube.

Wouldn't the fuel seek it's own level, much like water does with or without the crossover? If there is forward motion, wouldn't that cause the fuel to slosh around, thereby possibly forcing it to move around and quite possibly to the fuel pickup?

I could see where it might be useful if the tank set level/stock. I was thinking about the same thing the other day when my tank lift came in. With front raised up, the back of the tank will do the equalization? If that makes sense.

Vic,
Not sure if you run a tank lift. What about this experement to find out:
use a vise grip
and close the cross-over tube when the fuel level is almost at the lowest point.
Now keep on riding untill you have to change to reserve. At that point remove the vise grip to find out if the fuel in the tank levels from r/h to l/h side...
