I posted once before regarding my headlight, but I couldn't seem to duplicate the issue...

When I start the bike (07' 650r) everything works as intended. I ride for a while and have no issues, headlight stays on, hi/low beams work fine. However if I stop somewhere and turn off the bike, sometimes the headlight wont come back on when I start the bike again. Brake lights work, turn signals work, but hi and low beam dont.

It seems to happen only when riding the bike for an extended period of time, or in really hot weather, etc. If I let the bike sit for a while, and cool off, the headlight will come back on when i attempt to start it again. Any ideas what could be the cause of this? Or should i just start pulling plastics and break out a multimeter?

Just got home from work and it's dark out...but I do see that the frame ground is just sort of hanging there not attached to anything. Could this be responsible?

Hard to say for sure that it's the ground wire but it certainly sounds like a wiring issue, most likely a poor connection or solder joint. While I can't say for sure that it's not the ground wire it seems unlikely based on your description of it's current state, as that would most likely cause it to be consistently off.

Intermittent wiring issues often present themselves with fluctuations in temperature due to the connection points being of different density or different material altogether expanding and contracting at different rates. Unfortunately these are the biggest pain to troubleshoot if you cannot consistently recreate the failure. Sorry I don't have any great advice other than to get in their and start gently, slowly and methodically moving wires around until you can re-create the issue.

Good Luck.

This... start checking connections
