I don't think mine's well. Optimated the battery, started bike fine but on tickover the lights are pulsing, rev it up and they get brighter for a fraction of a second and then dim back to "engines not running" brightness. Haven't yet measured the battery voltage but its obvious somethings unhappy. I'll pull the reg/rec off tomorrow and see if I can dig out the potting compound and fix it, but I thought I'd ask if anyone has one sitting there doing nothing that they want to sell?
