8 coil stator magneto commonly used on 4-stroke 50cc, 125cc and 150cc GY6 scooter engines. Also sometimes referred to as a stator comp.

4 wires: Yellow, White end in a 3 pin female plug, Red, Blue in single pin.

Mechanics Note : 8 pole stator will work on any GY6 50cc 139QMB (and many others like 2-strokes) as long as you have a matching 8 pole flywheel rotor to go with it and have 4/5 wires. When you order a stator generator, be sure it matches the number of poles your rotor was made for. And in reverse, if you order a flywheel rotor, be sure it matches the number of poles on your stator. If you need both, order a matching 8 pole stator generator and flywheel rotor. These can come either AC or DC so be sure it fits your engines electrical system.
