AC vs. DC CDI — How to Tell

Most smaller and newer machines use an AC CDI. A quick test: turn the ignition to the "ON" position with the engine off. If the headlight does not illuminate, your machine is AC. DC CDI boxes are physically larger than AC units. Always confirm your machine type before purchasing.

Frequently Asked Questions

Q: How do I know if I need an AC CDI or DC CDI for my motorcycle?

A: With the ignition in the "ON" position and the engine off, check if the headlight turns on. If it does not, your machine uses an AC CDI system. If the headlight comes on without the engine running, it is a DC system. AC CDI boxes are also physically smaller than DC units. This AC CDI Racing Box is designed specifically for AC-powered machines.

Q: What engine sizes is this programmable CDI box compatible with?

A: This AC CDI Racing Box is compatible with a wide range of engine displacements from 50cc up to 160cc, including common sizes like 70cc, 90cc, 110cc, 125cc, and 140cc. It fits ATVs, pit bikes, dirt bikes, scooters, mopeds, go-karts, and motorcycles using the corresponding 4-pin, 5-pin, or 6-pin AC CDI connector.

Q: How does the DIP switch work on this CDI box?

A: The built-in DIP switch allows you to select different ignition timing and RPM limit settings without any additional tools or wiring changes. Simply toggle the switches to your desired configuration to optimize engine performance for street riding or racing applications. Always refer to your engine's specifications when adjusting RPM settings.

Q: Will this CDI fit my WAVE100 or CG125?

A: Yes — this CDI Racing Box is listed as compatible with the WAVE100 (part reference 30410-KRS-901) and CG125/CG150 engines, among many other models. Always verify the number of pins on your original CDI connector (4, 5, or 6) and select the matching option to ensure a proper fit.
