5 Pin CDI for ATVs, Dirt Bikes, etc. Version 3 Very popular 5-pin CDI fits many 4-stroke models of atvs, dirt bikes, go karts, scooters and mopeds.  Many engines require this CDI, including 50cc to 125cc.  Verify the number of pins and style of plug for best match of your CDI. This is an AC CDI.  Most of the newer machines are using AC CDIs. The easiest way to tell if your machine is AC or DC is to turn on the headlights with the machine turned off and the ignition in the ON position. If the headlight comes on, it is a DC machine; if it does not, it is an AC machine.
