Centrifugal governor and contact breaker plate are replaced by a driver, light disk and a printed circuit board.
The assembly of the pickup PCB takes place on the fastening spots of the original breaker plate, the magnet disk is fastened on the driver and can be easily adjusted by set screws. 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 Hallsensors. This has the advantage that the advanced ignition is precisely computed for each cylinder.

The original ignition coils can be used further. 9 ignition curves are available, selectable by a rotary switch at the box.
