Centrifugal governor and contact breaker plate are replaced by a driver, magnet disk and a printed circuit board.

The assembly of the pickup PCB takes place on the fastening spots of the original breaker plate, the light disk is fastened on a driver sleeve and can be easily adjusted. As an adjusting help a little LED on the PCB indicates the correct position.
Each cylinder has a self-sufficient ignition, i.e. two micro-controllers for two cylinders, thus two light-barriers. This has the advantage that the advanced ignition is precisely computed for each cylinder.
