If everything ran fine prior to the problkem I wonder if there's a chance you either hooked the solenoid up wrong or got a bad one.
 
here's another thought: i had a few weird electrical problems thruought last summer including my bike dieing intermittantly. It turned out to be many(all) of my wires going around the steering area to the controls. they simply broke down after time inside the housing and all made contact with each other. i ended up replacing both left and right controls and wiring harness. look under your tank and around your steering.
 
I've always wondered if there was a better way to route wires than through the headlight. You've got a lot of flexing in the wires there. I realize that you've got a lot of switches, lights, etc. in that general area so the idea's probably moot, but it gives a lot of credence to the "minimalist" viewpoint (no blinkers, gauges, etc.). I'm still going to run all of that stuff, but other than replacing the wires in that area every few years I don't see how to keep problems from happening in that area.
 
you've got power being supplied to the clutch switch by-passing the the starter button, when it should go through start button first (or bad start button contacts still), then to the clutch switch, then to the starter solenoid. check the wiring for a cross connection.
you've got 12 volts being applied were it should not be.
disconnect the start button wiring and see if the problem is still there.

It's a pretty simple system, the 12v goes to the ignition switch (you said it doesn't crank with the ignition switch off so the ign switch is good) then to the start button, then the clutch switch, then the solenoid. it's most likely the start button/switch that's bad (it didn't do it before correct?).
don't cobble it unless you want to join the ranks of being a hack PO...

I think your absolutely right. After removing the tank, checking wires, etc., the bottom line is that the clutch switch is getting power when it shouldn't be...its acting like the starter button is being pressed when it isn't. I dissassembled the switch itself and it looks ok, although I have nothing to compare it to to be honest. However, right before the wires for the starter button and kill switch enter the housing on the right grip, the wires were threaded in between the mounting brackets for the rear view mirror and smashed flat. I'm going to cut out the bad section of wire, solder the ends back into the starter button circuit and see if that doesn't solve the problem.
 
Check it with an v.o.m. (volt ohm meter) first. or use 12v and a 12v light bulb for a continuity test with the switch out of the circuit. do you have a test light? leave power to the start switch and disconnect the lead going to the clutch switch.
if the copper wire is not damaged shrink tube it instead.

I wonder if you could explain this a little more before I dig myself any deeper by snipping wires.

There is an orange (#1) and orange/white (#2) wire coming into the starter switch. As I read the wiring diagram that is the power to the starter button. There is also a green/yellow wire (#3) from the starter button to the clutch safety switch. And finally another g/y wire (#4) from the clutch safety to the solenoid.

So a total of four wires.

I know #4 is good.
 
Problem solved!

Problem solved!

The green and yellow wire that runs between the starter button and the clutch safety was fried from being pinched in between the rear view mirror mount and the handlebar. Not sure why that would have cause the clutch safety to start the bike, but at this point, I don;t care...its fixed.

Of course I did about 4 hours of disassembly that turned out to be unnecessary, but such is the nature of electrical problems I guess.

Thank you all very much for all of your help!

Thank you for getting it fixed!

Like many I've been watching this to find out how it turned out!

Another GSR victory!
 
Congrats! Another electrical demon has been exorcised!

Funny how one little wire can screw up everything, ain't it?
