That’s no good, too much rust = easy voltage drop (even a little) , we’ve been there. (or even a sensor somewhere else , having its resistance affected (ohms too low or too high on the wire, the ECU will trip)
Go under the bike and find your regulator rectifier, get pictures of it and also the connectors on your harness.
You have a long job but i am sure it will be worth it, you want “nothing electrical” to have rust , even down to the red battery wires etc.
Hyosung tried but remember UK rains too much!
