I understand this. What I am saying is that you are showing a step up transformer holding a voltage higher than the bike is producing at idle. What I am saying is that while it may be able to achieve this with little load on the system it likely will not be able to while powering the heavy lighting that this was all intended to power in the first place..
Just as you can wind with thinner gauge wire to produce more voltage but will lose wattage. You can't boost the voltage without sacrificing something.
