AC vs. DC – How to Tell
Most modern machines use AC CDI. A quick test: turn the ignition to the "ON" position with the engine off. If the headlight comes on, your machine uses a DC CDI. If it does not light up, it uses an AC CDI — and this unit is the right fit.

Frequently Asked Questions
Q: What engines is this 5-Pin AC CDI box compatible with?
A: This CDI box is designed for 50cc, 70cc, 90cc, 110cc, 125cc, 140cc, 150cc, and 160cc engines commonly found in motorcycles, ATVs, dirt bikes, pit bikes, go-karts, scooters, and mopeds. Always verify your machine uses a 5-pin AC CDI connector before purchasing.
Q: How does the DIP switch RPM limiter work?
A: The built-in DIP switch allows you to manually select different RPM limit settings ranging from 4,000 to 12,000 RPM. This makes it easy to tune your ignition for different riding conditions — from casual street use to competitive track racing.
Q: How do I know if my motorcycle uses AC or DC CDI?
A: Turn the ignition key to the "ON" position without starting the engine. If the headlight illuminates, your bike uses a DC CDI system. If the headlight stays off, it is an AC system — and this CDI unit is compatible. DC CDI boxes are also physically larger than AC units.
Q: Is this CDI suitable for racing use?
A: Yes. This CDI unit is specifically designed for performance and racing applications, including competitive racing builds on models like WAVE100, YX140, and similar small-displacement performance engines.
