I had my scooter stolen but found it later and it seems like they tried to start it by short-circuiting it. I smoldered back black wire from the ignition and the scooter gets electricity again but I can't get the engine going by pressing both handbrakes and when applying the front brake it looks like the scooter is accelerating on the spedometer and the disply shifts the setting between km/miles. I can't find anything else done with the scooter. Do you have any ideas what it could be?
