The stock 6-pole stator is actually a very simple device. There are 6 windings total. 5 of these windings are wired together in series and are responsible for charging your battery and supplying power to your headlights & auto-choke. Positive voltage flows from the stator through the the yellow and white wires. The black wire is ground back to the stator. It must be noted that these three wires are completely isolated from the ignition system. You can unplug the 3-prong stator wires harness and the engine will still fire up just fine.

The 6th winding wrapped up in white layering seems to be dedicated to supplying the CDI with AC power. The blue/white wire leading to the black magnetic pickup is called the trigger wire. This wire is responsible for telling the CDI when to send power to the ignition coil, firing the spark plug.

Shown in this article's picture is a 8-pole stator. The 6 and 8 pole stators are similar in function, the key difference being that the 8 pole stator as 2 additional poles dedicated to charging.
