EFI is not a step anywhere but sideways.
How so? From what I have been reading it seems like a step forward... But like I said, I will still prefer to work on carbs because I think that they are simpler.
It's heavier. Carbs atomize fuel better. It has it's benefits, but not enough benefits, in my opinion, to re-tool a factory. The real step forward is in the lubrication department. That independent firm in Australia that has a patent on their design is doing the right thing. I wish a smaller manufacturer that uses someone elses engines would give them the contract for their engines. Or someone else would buy the technology. I just really do not thing this status-quo two-stroke design is going to make a comeback as it sits.
Dunno what all this talk about being heavier is, its just something that someone said and then everyone repeated blindly.
A throttle body is often more compact and lighter than a Carb of the equivelent size.
The fuel pump and Injection controller box weigh sweet F-ALL
The battery would already be on the bike if it was an E-START bike like most enduro 2T's are now.
This is the throttle body which was going to be put on the TSS500 before things went sour. Looks much lighter than a carb.

No need to re-tool a factory as KTM doesnt make their own carbies, Keihin does... there would be no reason why itd be any different with injectors.
Orbital engineering has done more to hinder progress than help it. Their patents on the technology are stopping manufacturers from producing it themselves unless they pay an astronomical price to licence the technology.
The short term future for injected 2T's is a mixture of transfer port injection (quasi DFI) for fuel economy in the bottom and mid range and then uses secondary injectors in the throttle body for the top end boost.
I believe this is how the OSSA may be set up.
