Reply To: GV125S-EFI Only sparking on 1 cylinder
Get a picture of the regulator itself, and copy any part numbers written to it. And also post a second picture showing us what the plugs look like.
The regulator will say 14v idling (both cylinders need to fire first though so engine runs properly) and 15v max around 15k revs at the battery terminals.
If the reg is good, wonderful. Consider pimping the unit later on. I will know what to get based on what visuals you send me on here.
Stator tests = Your stator is fine. It’s too healthy to worry about it now.
