Re: could this lighting coil fit in a chinagirl?
The only way to fit it all inside the small cavity of the engine is to duplicate what Wonderful Creations has designed.
It attaches to the right side of the existing stator and uses the stock magnet.
From what I have read up in rider/ owner reviews, they are quite powerful for their size, I might add. Not like a full blown motorcycle system but plenty good enough for a powerful bicycle light system.
