Confirm your black-wire repair. Test that by measuring resistance between black-wire spade connector to chassis ground. Compare that to your earlier reading and what do you get?

Yep, no output on ECU-ignitor black wire to left coil pretty much confirms it's dead. Now WHY it's dead can be a mystery that's endlessly debatable. But there's no arguing that it's dead on left side. I think the short on black wire wiped out the driver-transistor.
Do one more test to confirm the left channel's dead.
- disconnect black wire spade from coil
- bridge green-wire from right coil to left coil empty terminal with test-leads/alligator clips
- perform 'noid light test on green coil, does it flash?
- perform 'noir light test on black coil, does it flash?
- how does bike run?
