The CDI issues have been resolved. The Jaycar cheapies work well - when the correct wires are attached.
The stator I was using had the high voltage CDI wires cut off and only the lighting circuit wires left. Novice that I am I used those. Wrong. It works on the RGV CDI as that has it's own step up transformer in the unit so it doesn't need the high voltage charge. In fact the RGV stator only has power that will be rectified. I don't know that.
Anyway, back to the current CDI set up. ...

I have had the engine running on an RGV250K CDI module but it had a miss which I suspect is the timing advance built into the CDI.
As the RD400 didn't have an advance curve I decided to try the simplest CDI I could find - Jaycars kit KC5466. No problem assembling the CDI and checking it's all OK but it requires an input of 350VAC...
I measured the output of the stator on one wire and got between 8VAC and 12VAC. A friend of mine tried a trick of putting one wire to earth and got 20VAC ...
