If you can find the switch connector, disconnect it, then try to start the bike. If it starts, go ride. If not, cut the kickstand switch off, making sure to leave plenty of wire to the connector. Strip 1/2" of insulation from the the wire ends. Twist them together and re connect to the wire harness on the bike where you disconnected it. The bike should start now.
Leaving the ends just twisted together would be bad, soldering them together and covering with heat shrink is the ideal solution, but if you're not able to solder or get heat shrink(available at any radio shack or harbor freight) A good temp solution is a solderless crimp (also available at radioshack). I believe the one you'd want is called a buttsplice

and then wrap it up in electrical tape.
