    Hi,
    My motorcycle develops the following problem once in a while (less than once a month at average, but sometimes twice within ten mins):
    Even at full speed the engine goes off and the display gets dark. When I'm fast enough I can restart it by simply turning the key to 'off' and 'on' again and pressing the starter button without stopping, otherwise I have to stop and do the same procedure.
    Any idea what could cause this problem?

    Sounds electrical. Have you checked the fuses? Dead battery? Loose terminal on battery? That's where I'd start.

    Are you doing anything in particular when it plays up, ie. bumpy ground, been through water?

    Good info. I'd also check the battery terminals first, just in case.

    It's none of those.
    I suspect it's the ignition switch since when the system goes off and I move the key a bit up and down it works again.
    Anybody there with a similar problem?

    Not really. I assume it's the ignition switch.

    It's definitely the ignition switch (not the magnetic, that ne with the key). There seems to be a small gap in the "ON" position between the most left and the most right position where the electrical current flow is disrupted. Unfortunately at times the key finds this position itself due to vibrations. Then the engine goes off and the lights as well - no fun especially at night.
    Any idea how that can be fixed without replacing the lock?
