It will be very hard to isolate the problem if the wiring system is still whole. You need to be able to 100% know every link in the wiring system is going where it should and the wires leading to them are a solid connection, believe me you might think pulling light bulbs is an unnecessary idea but a single miswired brake wire or light bulb can cause those symptoms. Unless you've physically traced every wire is going to it's proper destination you can't rule out a miswired wiring harness.
So if there's an alarm system you need to disable it by unplugging it completely. All the light bulbs it's a good idea to unplug them, this was actually advice posted by a previous poster. Basically if you have dim headlights you want to be able to isolate all the wiring going to just those headlights and light bulbs. Making it as simple as tracing one path, stator, regulator and headlight bulbs.
Draining the battery and having the lights temporarily restored also might still be a grounding issue. I would check continuity of the wires and connectors and just for good measure temporarily mock up a grounding probe. Then with the scooter running probe both sides of all the the connectors on the green wires of the now isolated headlights and also probe to see if grounding the heatsink of the regulators helps. This will determine if the ground is being lost anywhere, due to bad connections or even broken wires, as stated by previous posters. This is why you want to unplug all the rest of the bulbs so there's less to investigate if unplugging the bulbs doesn't lead to a diagnosis.
Not trying to sling mud but you seem very resistant to several people's good advice. This site is relatively new. So it's hard to really see who has all the real experience to give good advice. But the advice given is pretty standard, and even on this thread surprisingly consistent when it comes to diagnosing electrical problems. In this case have you done everything to isolate the problem and half split it to the actual component? Unless you pulled every bulb and removed all sources of extraneous grounds, and ground checked every green wire you can't say you have.
If you replaced the stator too that means you've replaced the regulator, and stator but still believe it not to be the wiring. That makes it difficult for me to believe you've done a wiring diagnosis. Next step if you don't want to do a complete wiring diagnosis, put a whole new wire harness in. You've already replaced all the other components already, and doing them multiple times obviously hasn't helped.
