Problem fixed! The poster who ended up being closest to the actual answer was... [insert drumroll here]... micbusathens.
Reinstalled the starter solenoid, then reconnected both the battery cable and starter cable but not the relay coupler since the problem had to be with one of those four lines. Checked the two pins on the solenoid relay which send 12v to other parts of the bike and both correctly read 12 volts. That left two other lines, a 12v signal which comes from the start button (Y/G), and ground signal which comes from the clutch lever position switch (B/Y)... need both to activate the solenoid.
Although I expected it was the start button, it was much easier to test for the ground signal using a continuity tester so that's where I went next. One end to the relay coupler (B/Y) and the other end to the battery (GND)... pulled in the clutch lever and nothing. Tried several times... nothing.
Took a look at the clutch lever next and everything looked normal including the two connectors on the postion switch. Then I noticed the wires leading to those connectors looked rather taut. Turns out when the bike fell, the right handlebar struck the pavement pushing it to the extreme right, which caused the other end to pull those two wires just enough to cause the position switch to jam. I removed the switch... it didn't even break... the plunger just popped back into postion. Reinstalled the switch and the bike fired right up.
Unfortunately it didn't fix the cosmetic damage which will cost a lot more.
Well, thanks to everone for chiming in. It was truely a learning experience. Thank goodness for this forum... and service manuals.
