haha, see, the funny thing is, that the stator produces volt-amps, to put it in terms that you can better understand. as the amperage increases, the voltage decreases. 100watt 12v lights will pull just under 8 amps, keeping the voltage low. a 70 watt load will only pull >5amps, wich will leave the passing voltage <20. the voltage regulator simply grounds the excess v.a. unlike a car, which controlls the production of power by the power to the windings, instaed of a perminent magnet system. because of running a max load all the time, there is no excess power to absorb/ground. if you were ever to run a smaller load, it would definately be nescicary, wich will probably be the case in the near future. but, you can still ride with the 100watters, untill a new regulator shows up, and then swap the bulbs out for some lower wattage bulbs, so they can be brighter at lower rpm's
