Reply To: No Spark !!! GV125-S Bobber 2022 (GV125S EFi)
Well it’s going to be a fuel injection one I assume, with the stator burned out the rectifier is almost certainly toast until that side is sorted it’s going to be a nightmare, if the voltage isn’t correct then the ECU will just play up.
Auto correct stator isn’t burnt and reg looks ok it just won’t spark at all
Hyosung regulators have always (even the chinese £10 clones) been smoking the bikes or causing all sorts of cvharging issues.
An ECU is not cheap or possible to acquire right now, it doesn’t take much to fry it as Simon said.
If you intend to keep her for long, this will be the most important – numero uno – investment on the electric side of things.

Test your stator as simon says and report back the readings.
Use this as a guide (ignore that it says GT125, the instructions apply to all Hyosungs as they still use 3-Phase stators):

Simon knows enough , go with what he says if i don’t reply. 👍
