There use to be some bloke on eBay who claimed he could replace almost any Bosch ignition system with an electronic ignition. Can't seem to be find his ad any more. This upgrade would of course be possible for the technological-minded, which I'm not.
In any case I recently found that the same old points ignition system that was used on my vintage mowers is still alive and well in Germany and Italy. Ducati are in fact still making them for scooters and mopeds. They work perfectly. Only difference is the central gap for the shaft is a bit smaller on the plate, but as these are made of soft alloy it is a very easy job to file it out a few mm wider.
