The CDI box for this bike is p/n M04016000 there is a black wire that comes out of the CDI that is supposed to be connected to a chassis ground. I do not see your CDI box in this picture. to the best of my memory the CDI box is approx. 70mm long x 15mm x 15mm there are 2 x 3 wire connectors going to it, one on each end.
Good luck.
I remembered this when relooking at your forum post. The original Motoplat ignition has part of the CDI unit in the Stator and the rest of the CDI unit in the HT coil. PVL makes a replacement HT coil that should work if the stator is still good. I believe that Rex's Speed Shop sells this replacement PVL replacement HT coil.
I think if you removed one of the screws holding the stator plate there would be a witness mark. If there is only one witness mark it would be unlikely that the stator plate had ever been moved, therefore it is in the correct position. That is what I think .
cette pièce qui tombe est probablement le jet d'aiguille, il est fait pour s'adapter correctement d'une seule façon. certains des jets d'aiguille s'adaptent parfaitement et d'autres assez lâchement j'espère que cela répond à votre question je vous ai répondu en utilisant google translate
