85hp Enduro 2stroke No Spark - Peak voltage testing help??

[Drifter1]

Update:
This is a friends motor and we have not had much time to progress on it.
We had access to a used Pulser coil so swapped that and no change.
We just had a yamaha mechanic look at it and found the same readings as me and he has said it’s the CDI. So according to him the “New” CDI that we installed initially was faulty and we need to replace it again.

I will update once the final solution is confirmed.

Thanks

Was the new CDI a genuine Yamaha part or some kind of cheap aftermarket brand, or even worse a second hand part?
