Orbital Engine Corp's patents are due to expire or have expired on this, so theres a chance 2-Stroke DI might make a comeback.
Here's a 2022 article:
Aprilia’s Fuel-Injected Two-Stroke Concept
As someone stuck in a newly 3rd world country (South Africa) who has been all over Africa, here's what I think went wrong:
"You want to come here and fit this to my engine, as a test, for free? Sure!
"
"you want ME to pay $300 for it!? Uck Foff!!!
I don't care that I'll make the money back in a year! WhereTF am I supposed to find $300!?
Go get the govt or someone to sponsor it for freeeeee!! (Not A chance!)
And BTW I also want $300! ...er... for the time and trouble of fitting it"
ie: 'Pearls before swine' - Just plain broke - No foresight evolved.
