I'm sure there are challenges in a wall of death / globe of death situation, but I'd think that negative-g would not be one of them? Quite the reverse, I'd have thought...
The “orifice” was not for making fuel flow at negative gs, but for limiting the fuel after (once normal forces returned? The article is not clear) so there wasn’t too much fuel causing a rich-cut.
So possibly motorcycles could have the rich cut from bottoming out in the sphere of death?
