Howdy,
I did the Eastern Beaver mod, love the brighter headlights too.
I don't know what the starter mod is, but I will certainly do that as well, once I know what it is. I do remember reading something about the contacts in the solenoid.
When you did the EB kit did you check the Ign switch and the wiring back along the loom to the connectors for signs of overheating? If the EB significantly improved your lights it indicates that the switch had got quite bad and likely overheated, that heat can radiate back along the line. If the wiring and/or connectors have been effected it gives the same symptoms.
I fitted a bypass relay (not EB) to a friends Rocket because he had all the symptoms of a bad switch but it wasn't the switch, it was the fist connector along from the switch. It was so bad it had to be replaced with individual inline splices.
