i tried looking a little for you and had no luck with the wiring diagram.
here is a place to try maybe they can help you.
www.yamoto.com.au they have a contact page and can email them maybe they could send you a diagram,just a thought and maybe worth a try.

i read that you repainted the frame did you scrape the paint back off where the grounds wire go.i know some of us buggy riders have had trouble with paint causing the buggy not to get good enough or weak ground to fire the plug.just another thought.
