This is a very interesting story that is (at least claimed to be) part of my family history.

My family stems from a group of travelling motorbike stunt riders back to the 20's. They did the wall of death and later the globe of death, and had to solve this problem in their bikes.

The family story is that we helped win the battle of Britain, as Miss Shilling read the about the idea in a motorcycle magazine that covered my families show. There is a lot of evidence on what Miss Shilling did, and that my family did the same modification to their bikes prior, but the lack of a link between the two leaves this as a half truth / half myth story

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?
