A high performance “CDI” will advance the engine timing allowing for higher low rpm torque and higher top end speeds. The installation process is simple and the results are instantaneous. You simply unplug your old CDI, plug in your new High Performance CDI and bam!

Does a racing CDI work?

The stock CDI would have slower charging capacitors with a lower max RPM, while "racing" CDI would have faster charging capacitors and a higher max RPM. You won't notice a difference at all unless you push the engine to the rev limit, assuming your engine can reach the higher rev limit allowed by a "racing" CDI.

Can you bypass a CDI box?

You can temporarily bypass a CDI box for troubleshooting purposes. The box amplifies the small signal generated from the spinning magnet located in front of the pickup coil in the stator, just before top dead center (TDC), when your fuel-air mixture is ignited. The box can't generate continuous sparks.
