Ok,
I finally got my bike running this past weekend! It's not as nice looking as my old bike, but at least I've got something Note, that the first paragraph that follows is the executive summary. The following paragraphs are at a more technical level.
CAVEAT: My spark plug may need to be tuned!
As promised, I measured the output voltage from the white wire, in the hopes of eventually designing and building a high-quality lighting system for these motorized bikes. The output voltage was something like 20V to 25V. When loaded with a 10kOhm resistor, and the motor died, implying that the motor can source less than 0.06 Watts! (This is why I'm guessing I need to tune my spark.)
The setup was as follows: I duct-taped a "ground" wire to my steering column. A 3' wire was connected to the black cable. Measurements were made between those two wires.
The output waveform was not a nice, beautiful looking, sinusoidal wave, but rather a very strange looking waveform. The positive swing looked half sinusoidal, but the downward swing shot off the bottom of my oscilloscope. Until I can photograph my oscilloscope, this is the best desc available
The white-wire output was connected to a diode bridge rectifier (DF005M) and a 0.1uF smoothing, electrolytic capacitor. Output was loaded with the 1MOhm voltmeter and a 10kOhm resistor. Bike would not start with the 10kOhm connected.
