This NCY Performance CDI works on most AC current GY6 50cc/150cc scooters that are made in China using the 139QMB/157QMJ enigine. Higher voltage output, agressive mapping as well as the removal of your rev limiter make this ideal for custom builds or just simply trying to get a few more MPH's. A billet aluminum case protects this from road debris and looks cool too. Confirm the connector design you have and that you have an AC ignition system.
The system voltage is raised up to 400-600 Volts by a transformer inside the CDI module.
This part is for off-road use only and carrys NO WARRANTY. USE AT YOUR OWN RISK.
