It will replace the pickups and rotor on the crank end as well as the ignitor. Check the wiring diagram to be sure what other functions are tied to the ignitor. If it's things like side stand switch, you can eliminate that, but if if feeds the tacho or anything else, you may need a workaround. I don't think that will be an issue, but worth checking.
Regulator and rectifier are not usually combined in the ECU because the regulator generates heat and the ignitor is easily damaged with too much heat.
If your bike has a mechanical advance unit, you are golden, but if the ignition advance is generated by the ECU, that could be a bit of an issue to overcome. In that case you can probably get a mechanical advance unit for a different model and make it work.
