On the bikes that use the separate regulator and rectifier, unplugging the regulator does remove the power to the rotor.
On those bikes power goes to the regulator then to rotor, then ground.
On the later combo reg/rec power goes to the rotor, then to regulator and the regulator grounds the rotor.
Unplugging the big plug in the wire bundle coming from the stator just above the engine works on all years.
