Curious about your vendor resource, since there appears to be an abundance of bogus performance components.

Somewhat puzzling how a performance AC-CDI advances the timing firing curve, due to the fixed positions of the pickup coil and outer flywheel trigger magnet. Since there are two flywheel triggered impulses to the CDI to fire the sparkplug during a 4-stroke cycle (one is typically wasted), perhaps a performance CDI circuit is actually delaying the sparkplug impulses so the effect is an advanced firing curve.


This vendor offers an original type GY6 AC-CDI and ignition coil for around $20 shipped.
