The wiring on a modern dirtbike would be even simpler; because breaker points ignition no longer exists as it has been replaced by things such as CDI (capacitor discharge) systems.

The bike used in this example is a 1984 Honda XL100 (S)
<p>I have a 1977 xl75 with points also and it looks exactly like you engine, I also have the 4 wires but they are all white., Can the green wire be disconnected from the neutral switch? Thanks for the video</p>
