jBernard:
i was about to tackle this on mine until i decided not to. had the same throttle body and all.

looks like you know what you are doing already, but look into some of the bashee forums and rz350 (?) forums, there have been several 2 strokes done over to EFI.

look into the Microsquirt EFI system. its by far the smallest and most customizable. also not overly expensive.
you'll need to make a bracket for a hall effect sensor inside the ignition cover to determine crank position and speed. that will feed into the MS.
to tune it correctly you'll need a bung welded into the pipe for an O2 sensor and those things self destruct after not to long when they get any contaminants on them (oil from premix) so it should be hit or miss there on if it will last long enough to tune.

what are you going to use for a battery/charging cap?

Kawasaki/ducati:
Thanks for the input!, we have used the original kx 450 stator and flywheel which provides the charge  required to
run the efi system
 Will look into those other systems, but for now we have put it on hold due to other work in the shop!
if anyone here in OZ is looking for a good online Motorcycle store check our site  bargainbikegear.com.au
  thanks again John

vagassasson:
Very nice looking mod I'm sure a lot of guys here would love to see what they could do with some efi mapping. I for one would buy a kit to do this in a heartbeat 

alexander-vmann:
so did this thing ever fire up? :-o

Candyman:
No updates after a year.... not a good sign...
Hopeful but not holding my breath..
