Some might...
I would hesitate to try though. The sensor for stock ignitions from other bikes will be a bugger to adapt to the 750. The advance curve is usually built in to the ignition module on modern bikes, and is unlikely to be ideal for the 750 and you'll need to disable the mechanical advance.
The installation might take a ridiculous amount of time and may not work, getting a Dyna or Boydsen aftermarket electronic system made for your engine is the better approach.
