Is it 12 volts , plug in motor, and starter motor turning?

Gotta test it under load.

Well, looks like it should fire. Now, that's plug in motor, trying to start?
Here's another approach.
Leave plug screwed in head, pull wire, stick a plug in it, hold it against the block, hit start.
No spark?
Pull plug from motor, now, the starter isn't loading the battery near as much without compression, then, if no spark, yeah, probably cdi.
But you gotta get the plug against the block, ground it.

Yeah, dude, nobody wants to say
replace the cdi. They cost a lot. So, it's best to test, test and test again
before deciding..
There could be more tests, I don't know.

make sure you're getting 12v to the cdi, then I'd say replace.

Just to confuse you, here's a pic from a 96 and the pin out for a 86.
I don't have both for both.
My guess is the orange/wht is 12v

I'd check out 1 more thing...
the timing pickup.

specified resistance is 200-240 ohms.
also check for any shorts to ground, shouldn't be any.

I wish I understood this part of the bike better. I'm good with some of it, but the carb and charge circuit and the magic of the cdi aren't my strong points.
The smell of burnt electronic stuff is a real consideration. And that the coil was messed up is another indicator, then, no spArk,, I'd be ready to call it dead... If someone else has another idea before you drop that cash,, cool.

You're doing a lot better with English than I'd do with French.
Did you check out the old cars? All French..
