Transistor assisted ignition for vintage scooter

Have you tried a motorcycle forum?

Or, the Facebook group, 'Cyclemaster Help Desk'

This quarter's issue of the East Anglian Cyclemotor Club (EACC) magazine includes an article about changing a magneto with a Chinese CDI system at £13. (It's where the FB suggestion above came from).

I've finished with the magazine - if of interest, send me a PM with address and I'll stick it in the post.
