The majority of contemporary motorcycles include CDI boxes (Capacitor Discharge Ignition) technology that regulates the timing of the ignition spark and aids in smooth engine operation. Install a conventional points-based ignition system The spark timing on older motorcycles was managed by points-based ignition systems. You must take off the CDI box if your bike originally came with one and install a points-based ignition system instead. Consider using a magneto ignition system because it can operate without a battery or CDI unit and produces electricity. You can buy and install a magneto ignition system on your motorcycle. Utilize a battery-powered coil ignition system Another option is to utilize a CDI-free battery-powered coil ignition system. It's vital to remember that operating your motorcycle without a CDI module can be risky and could harm your engine. Additionally, you can notice a reduction in power, decreased fuel efficiency, and trouble starting your bike. It is advised that you get advice from a qualified mechanic before attempting to use your bike without a CDI module.
