Has anyone considered changing the I believe single tooth in the CB Performance cam trigger to a missing tooth variation?
I.E. more teeth?

Seems to me you could have any number of teeth present or missing as long as the "processor/program" understand what the sensor it outputting (number pulses and missing pulse) .... Its not the actual "cam sensor" in reality, but what the pulse train is interpreted as.... Many distributors (various application in auto world) use same "star wheel" concept (proper term?) to trigger ignition so its mainly a matter of what you ECU interprets and reacts to...
All this cam sensor in this application is signaling CB's box that #1 cylinder is at TDC on compression stroke (or something similar) so ECU know where it (engine) is in a sequence for sequential ignition and/or injection.. In this case its no more than a "index" mark ...You can probably make it anything you want as long as ECU understand what its (sensor) doing...
You can probable simply take something like a Compufire module (not Pertronix) and poke out 1 magnet out of top hat and have 4/1 pulse generator... OR poke out 3 magnets and keep 1...
