This capacitor discharge ignition (CDI) module, also called an ignitor, fits gas scooters, ATVs, dirt bikes and go-karts with modern 4-stroke GY6/QMB139 or Honda-style engines. It is meant for engine sizes of 50cc, 90cc, 110cc, 125cc and 150cc. It is common on 50cc, 125cc and 150cc scooters, and on 90cc and 110cc Chinese-made ATVs and dirt bikes.
It connects with a 6-pin rounded connector, as pictured. The module includes a rev limiter, which limits the engine's RPMs.
This is an AC CDI. It will not work on KYMCO scooters, which need a DC CDI. A CDI module from a 4-stroke engine cannot be swapped with one from a 2-stroke engine, because the two need different engine timing.
