i feel for you. my mom did the same thing to me when i was in high school (1994). actually it's pretty simple. i can speak for 90's honda sportbikes, but the concept is likely to be the same for the kawi's too. basically what happens when you turn the key is that there are 3 wires that make contact with each other. if you can get those three wires shorted together underneath the ignitions switch assembly, then you will have power to start the bike. keep in mind that the wires are like an 8 - 12 guage so we're not talking about light current duty, so don't plan on shorting them together with some bread tie wrappers. also as long as they're shorted, ur lights and computer is constantly on.
the second that the contact between the 3 wires happens, the bike will shut off, just like turning the key to the off position.
i know this to be true with the 90's honda's because i too was in the same situation with a salvage bike that i'm still building. before i got a hold of an ignition assembly, i just found a matching connector with bare wires on the other end and shorted them all together, which acted like an acutated key in the ignition.
unless ur theoretically incline with basic electronics, i wouldn't bother with this modification, which actually is unsafe.
also ur original key could possibly have the key code engraved on the side or check some paperwork associated with the bike; title, maintenance reciept, maintenance log, owner's manual. the key code may be listed in one of those records. i doubt that the vin provides the answer to how the key will need to be cut.
