I know I won't be more helpful than above comments but I also would not bother about this. It will be way, way more trouble to set-up this correctly to finally end with only cold-starting as being marginally better (assuming everything else is at least equal to well tuned carbs...).
I suggest you go for it!
I've been considering the EFI swap using zx-10 throttle bodies and a mega squirt controller for the past year. I'm on the edge of putting it together over the winter since I have to pull the motor anyway.
Somehting for everyone to remember....It's not always about making a great machine better. Sometimes it's about actaully doing something new, having fun doing it and gaining the experience along the way!
