the drangfly system has 2 magnets , i could not get mine to work, sent it back and they tested it and said it was ok, still could not get it to work, so gone back to points and the bike now starts again.
Thanks Ken. Its a bit of a concern when you've laid out good money. As I said, the Accuspark I fitted to our Scott never fails. Obviously a different manufacturer at source. We are going to try a Sovek (Jawa) optically triggered system on our sprinter. At around £40 including a twin coil I can (almost) afford to be disappointed.
