Hi, I have obtained a bike without a key and am trying to get a key made for it. I cannot figure out how to get the seat to come up or how to get to the ignition between the speedometer and tachometer. I was told by a bike shop the key goes to the ignition, the helmet lock and the release of the seat. If true, is there any way I can retrieve the numbers from the helmet lock or the ignition in order to have a key made for it. Are all the numbers the same for the same type of bike? OR how to I remove the housing over the ignition in order to get the number that way? Help
