Answer
Hi Mark.
 You, my friend, have fallen victim to the most insidious problem to plague motorcycles since the safetycrats forced installation of sidestand cutoff switches on bikes.  A bad sidestand safety switch or a bad clutch switch.  Most likely it i the sidestand cutoff switch that is the real culprit of the two.
 You can either replace the switch or remove and bypass it.  The choice is yours.  If you choose to bypass the switch, then make sure that you have the repair manual to show you the wiring layout, because you will need to connect two of the 3 wires in the switch together, but without the manual you will never know which 2 until it works.

Good luck and ride safe.
