same post I put in your other thread...

I searched Google and found this Cruiserman's Video that may give some suggestions.

I can't think of "anything particular" to look at on an F6B.

Make sure the same key works in the ignition AND the two locks. Open each saddlebag with the key ON to ensure the "OPEN" switches work.

The bike is covered in "tupperware" plastic parts which could cover up hidden damage. Look at all four plastic panels below the seat and gas tank, two on each side, and maybe ask the seller to pull each one off so you can see behind them. They're easy to remove after you've done it a time or two.

After purchasing I would change all the fluids and the air filter so you know it's been done, which is common sense.
