2009 Kawasaki Concours TBs - Electric "Choke"

[chsmadden]

I've wanted to convert this little '74 Alfa Romeo I've got to EFI for a while, because a 2000lb car with a 2L engine that gets 13MPG should not exist. I got a nice deal on some complete, really low mileage TBs from a 2009 Kawasaki ZG1400 Concours, and when they arrived yesterday I discovered they have this weird stepper-motor choke setup of some sort I decided I can drive with the MS2v3 board I have.
They close down restricting the airflow quite a bit, and when they're in the "fully open" position a small cam on the side cracks the main throttles a bit. I'd assume this is a cold-idle mechanism, but it makes me wonder how this is supposed to work? During cranking should the chokes shut, and when the engine fires open them up to produce a fast idle? Or should they sit at the neutral position (about 30* off of level) when cold and open up to fast idle when the engine starts? Unfortunately the bike these were pilfered from had a pretty sophisticated EFI system that I didn't have the privilege of witnessing running before these were removed, so I have no idea what the behavior of the chokes are during cold and warm starts.

If this is a fast idle system, you should theoretically be able to set it up like it's a stepper IAC.
