Not sure if your unit is AC or DC?
AC or DC?
Most engines generate alternating current to power lights, accessories, and to provide the necessary spark for the engine to run. If your engine was built prior to 2008 the odds are good it requires an AC CDI. A DC CDI is wired to the scooter's battery and uses the 12 V +/- drawn from the battery to supply the voltage for spark.
In order to get the proper replacement CDI you need to determine if you have an AC CDI or a DC CDI. A standard direct replacement AC CDI will be smaller in size than a DC CDI, measurement specs are listed for each of our part numbers. DC CDI's are larger because they contain a DC to AC transformer.
Another way to figure out the type of CDI your scooter needs is to check for voltage at the CDI. Turn the scooter key to the "On" position and, using a test meter or test light, check if there is current at the CDI. If there is 12 V at the CDI it is a DC CDI, if there is no voltage at the CDI it is an AC CDI. This is assuming the battery is charged, of course.

The stock CDI restricts the maximum RPM causing a significant loss of power
The stock CDIs on all buggies have a rev limiter that restricts rpm to about 5500. This Performance CDI has NO Rev Limiter and allows engines to achieve up to 9500 rpm. It also advances timing as the rpm increases to max out performance. Keep in mind that while this CDI will allow higher rpm, the CDI alone does not increase the rpms. The CDI works in conjunction with other installed upgrades to achieve performance.
Unplug and pull your stock CDI out. Carefully compare the connector plug to the picture to make sure it matches exactly. the pins should be facing the same way as on your stock CDI.
