If you throw in the total of the parts within even a simple 2t carb, I think you might even reduce the Number of parts on a DFI'd 2t. I'm of course, fudging a hell of a lot, and just choosing to look at the ECU/ CPU , sensors and injector itself as single unit items........... but, we don't /can't get CDIs, ECUs in component break down (into parts) form , and injectors / sensors, to my limited knowledge, are also made as / regarded as, non break down items.
Mind you, there are a hell of a lot of ways of doing a DFI 2t. Lets hope the blokes who design them, believe in the KISS concept.
The thing to keep in mind, is that it's not a good business decision to make bikes that people don't want / can't afford to keep running.
Cripes, even Bill Gates has just invested 26 million in the opposed piston 2t. If he can be behind the cleanliness , simplicity and efficiency of a 2t, there's hope for 2t acceptance amongst the great unwashed.
