No way in hell do I want any kind of injection on motocross 2-strokes. Totally defeats the point of owning a 2-stroke for MX - low cost, light weight, easy maintenance.
I can *sorta see the point for off-road where ease of tuning is important and absolute outright power is not so much. But for MX, there is no point to injecting a 2-stroke. Don't be afraid of some carb brass. The settings are all figured out.
I think TPI with separate oil is overly complicated, but a TBI running on premix would be sweet!

removing the oil tank, pump and injector as well as reducing to one fuel injector and simpliyfing the cylinder (no ports) would make for a simpler, cheaper bike, but would make it much more user friendly.
I just want a 125 that runs the same every time. I would give up 3 HPs and 3 kg for that.
On my 125 with the carb setup, I ride from 800 - 5,500ft and from 40 - 107 degrees F. Across all of that I change the needle 1-clip and the pilot 1 size. Not a huge deal. If my conditions were more "average" I wouldn't need to change at all.
Vital MX: "We really need cheap, affordable, uncomplicated, light weight, entry level 2-strokes to make MX more accessible."
Also Vital MX: "Let's put 10 lbs of expensive battery, injectors, pumps, and complicated electronics on a 125."
And I stay with it: would trade in 3 hp, 6 pounds and 500 bucks for a always perfectly running 125!
But i think e-start is unneccesary. Maybe i just like being tortured when im tired.
No, TPI shouldn’t be compared to Beta or Sherco or a 15 year old Yamaha. It should be compared to the bikes it replaced. And it is unquestionably heavier, softer, and more complicated than the bikes it replaced.
Drilled the holes in the fuel resovoir around the main jet, adjusted the height of the swimmer, cut the slide to a number five (I think), changed all the brass including switching to a S4. All of it.
Like I said, it‘s running good, just needs an adjustment here and there, no big deal.
However, I only ride ocassionaly and it would be nice to have the peace of mind to just know: it’s gonna be crisp and safe every time, no matter if I ride sand in Italy in the winter or hard pack in Germany in Summer at 3.000 feet. Just like a EFI-4Stroke (or does anybody miss messing with the accelerator pump when it bogged from time to time???)
What about new pictures of the 2023 bikes? All the factory riders should be on‘em right now.

So, what would be the simplest, lightest EFI option for the two-strokes? Is Premix-TBI possible without a battery?
