Sounds like a faulty stator unit, because if the CDI can’t sense it, it won’t send any sparks to the coils itself.
Did you also measure primary & secondary resistance of the ignition coils fella ?
Also if you can, remove the “HT CAP” thats on the coil itself. Then put your meter to 20,000 ohms.
Measure the HT cap on its own, tell us the resistance. The black caps are common to fail the sparks due to heat damage after a long while in the bike, since down the plug hole gets very hot. Though I would normally suggest to just upgrade to the heat resistant rubber NGK caps (NOT PLASTIC ones , they will crack!) , but if the black caps are OK , then go on amazon and look for “MAGNECOR HT WIRE” , these HT wires are great for maintain a consistant connection between the CAP and the Ignition Coil itself.
