well, the flywheel pretty much tops out around 7k+rpm, so, basically, the stator should put out 200watts from the lighting when you are in the pipe........but that's down at 10v and under. it generally keeps the voltage high enough for decent light output around 70% load, and that's 2krpm+ (a little higher than idle, like just cruisin around) the 150 watts is only 75%, so it would work ok, unless you have the tail light(13watts), and, of coarse, the stock harness ground isn't ideal for over 100watts, but will work...
