SO in a nut shell, how many more amps and volts can we use without draining the battery so to speak while riding?

The latest from Kymco USA Steven Oliver, Director of Service and Logistics the stator is rated at above 12 amps @5000 rpm at 14 volts(assuming regulated output. There is NO WAY to ask the question right the first time to get the type of answer needed!) which gives about 150 to 165 watts. Total available. Now I will measure the amps when the bike is running and maybe get the difference.

Side info: our three-phase regulator-rectifiers are the "shorting" type meaning they short the stator output to ground to regulate the voltage output of the system. This also means the heavier load on the system LIGHTENS the waste heat load on the regulator. Of course, this also increases the heat load on the rectifier!

Wow, I guess my information was pretty useless. That's a huge difference.

I was kinda wondering about 160 spare watts! Both engines should be swinging the same alternator capabilities considering similar displacements. Steve said the design was pretty close to save weight and minimize drain on the engine.
