NCY Performance CDI (AC, 6 Pin); GY6, QMB139

This NCY performance scooter CDI igniter module works on most GY6 50cc/150cc scooters and ATVs made in China using the 139QMB/157QMJ engine with AC voltage CDIs.

Benefits:

1. Higher voltage output up to 400-600 volts via a transformer inside the CDI
2. Aggressive ignition mapping increases power throughout the range
3. Removal of your rev limiter.
4. The billet aluminum outer case protects the CDI from road debris.

Compatibility:

139QMB-based 50cc / 80cc engines with the following engine codes

157QMJ-based 125cc / 150cc / 169cc engines with the following engine codes                

If you do not see your engine listed, if it has "QM" or "FM" anywhere in the engine code, and you have confirmed that it has an AC-based CDI system, this CDI probably works.

Specifications:

• Size: 6 pin connector
• AC voltage CDI systems only.

Notes:

1. This part is for off-road use only and carries NO WARRANTY.  USE AT YOUR OWN RISK.
2. Please confirm before ordering that the connector design will match and that you have an AC ignition system.
3. This will not work with any Genuine 50cc scooter, a 1952 Nash Rambler, nor will it fit a 150cc Wolf Jet II. The Jet II is a DC system.
