That's weird, because in the picture with your first post in this thread, your petcock's handle points forward, which is the "run" (normal) position, not "reserve".

And by now you probably realize that in the "run" position, the petcock drains fuel from the tank through a tube that sticks an inch or two up in the tank so it cannot drain from the bottom, and in the "reserve" position it DOES drain from the bottom of the tank via a shorter tube.

PS: From the manual:
Tank contents: 3.7 gallons (includes reserve) (California models: 3.4 gallons)
Reserve: 0.8 gallons.

PS2: I switched to reserve yesterday at 196 miles, after the engine stalled at a traffic light, with the road sloping down slightly. I rode about 20 miles and then filled up with almost 3.1 gallons. 70.5 mpg for this fillup.
