So, i ordered the CRF 50 $15 ignition. of course, things never go as well as you hope, but I was able to make it work.

I used my (spare) Kukosan ignition as my reference. I have a Taig lathe, so i can run the ignition up to about 5K RPM. (I can go 11K with my mill, but i don't think that i need it for this).

Anyway, i measured the advance of the CRF 50 ignition and i compared to the stock ignition on my GG ec300. Low speed and high speed advance are about the same! I used my timing light, and both advance zones are within a degree of each other. I don't know how the trials bikes are, but combustion is combustion, so it would probably work just fine.

Anyway, if you find yourself with a dead CDI, you can fix it for $15.

I haven't put this on the bike yet because it's still cold and snowy. If i have time, i'll mount it to the bike and see how it works. It seems fine on the bench.
