Not sure who you are addressing here (no Jim in this thread as far as I know) but it is nothing short of fascinating.
I replaced the six carburetors on a KZ1300 with fuel injection; initially it was a stock system that Kawasaki fitted these bikes with but only in Europe. But as parts are no longer available, I went over to a Megasquirt controller and set it up. Overall, it worked well but I was using throttle bodies and fuel injectors made for that engine, which made it somewhat easier but also harder in some ways; I had no idea of the capacity of the fuel injectors and so had to back the size out of the data I gathered while tuning the system. Normally, one starts with injectors of a known size and calibrates the system to accommodate them; I had to go the other way and set a PWM width to a reasonable amount for a given RPM, then run the engine at that speed and adjust the initial parameters of the look- up tables until the mixture fell into the right place. Knowing how large the cylinder was, the RPM, the throttle opening and the injector 'ON' time and the injector size can be reverse calculated.
As I said, a fascinating thing to do but also quite involved and expensive, even if T.B.'s and fuel injectors are available that bolt on; it would be even more difficult if one had to fabricate adapters for throttle bodies, adapt throttle linkage, etc., to a bike that was never available with F.I. in the first place.
Best of luck if you do try this.

Thanks Jim.
If I do decide to pursue my own design I will try to make it as affordable as possible. I have 5 bikes on my property that could use it.
I think it would be a very interesting and learning project
