I have installed motorolla voltage regulators in two of my xs1100's and a Well's VR (no longer available) in one of mine. I am still using the OEM rectifier unit. I think I paid $12.00 each for those units. The Wells unit works great and the headlight does NOT dim at idle. The others do dim but I think the motorollas kick on at about 1500 RPMs with the headlights running on those bikes. One of the problems is that the headlight bulbs are higher wattage than stock and I really don't think that the voltage supply to the regulator is enough to its internal electronics. If you want to see how it is hooked-up, see the following link:

Oh, one more thing... forget about the specification for the 83 Audi 4000 car. I think this was a mistake on the regulator's box. I have more information for anyone who might be interested.

www.partsnmoreonline.com[/url] that made my RD350 crank out 13+ volts at idle, it works great, but you have to modify mounting a little. Newtronics makes one, but I think the size and mounting holes won't work out as well as the one I bought from partsnmore.
The other possibility is that the permanent magnet(s) in the alternator just ain't what they used to be. I will look at manual to see if it can be disassembled. If I can find out the magnet(s) spec in Gauss, I can measure it at work and see what mine reads. If its the magnet, there are two ways to fix the issue. First is to replace or remagnetize the magnet(s). The second is to compensate with more field current at idle. A more modern reg/rec with higher output current capability would probably fix this too. It's possible that my RD350 had a weak magnet(s), and the new reg/rec compensated for this.
These bikes are still great, but if the charging system continues to deteriorate we're all gonna have problems.
