The way to really "improve" ignition would be a dual plug head. For instance, my airplane had dual mags and 2 spark plugs per cylinder. During runnup you switch to left, right, and both at 2000 rpm. I typically saw a 100rpm (5%) drop going to either single mag vs both. For the plane, this was not so much a performance feature as a safety feature (ignition out at 4k feet will probably not end well). The effect of dual plug heads is that the fuel burn is quicker and more even. Believe it or not, it can also help with detonation problems, especially with hi-compression pistons (which the Savage doesn't have).
With a motorcycle you don't need completely redundant systems, but dual plugs is fairly easy to implement by attaching the two plugs to the opposite ends of the secondary on the ignition coil. This also eliminates any timing synch problems. Then you only need to tap the head for two spark plugs on opposite sides of the combustion chamber. Of course, this must be designed in, because on the Savage head the spark plug is already near center.
