The CDI itself is simple to fit, just unplug and remove your original CDI and replace it with the Readspeed item. However your ignition will need setting up using a strobe.The 4-stage unit offers an easy, fuss-free way to allow you to alter your advance/retard ignition setting quickly and easily by simply turning the switch to the desired setting. It can be altered depending on your engine’s characteristics, or even the quality of fuel you’re using. If it’s pinking for instance, just alter it to a safer setting.
