How "Reserve" Fuel Works on a Carbed Bike

There seems to be a number of people here that believe that there is a separate section in the fuel tank where the "Reserve" fuel is stored. I hope this clears it up for you guys.
There is no separate reserve, section, divider, compartment, etc. in the fuel tank.
The petcock pickup tube has 2 fuel holes, one for the normal ON position (upper hole) and one that's used when you switch to the reserve position (lower hole). Once the fuel level drops below the upper hole, you are out of fuel until you switch the valve to Reserve which opens the lower hole.
OK, it's a quick and dirty drawing but it shows how the reserve works.

Standard petcocks are great, but only if you remember to turn them off at the end of every ride.

It's pretty simple really. The high lubricous properties of synthetic blinker fluid speed the flow of electron molecules through the blinker circuit. The same properties reduce friction along the electron path resulting in lower operating temperatures. Blinker fluid should be replaced at each scheduled service interval.
Dino Blinker fluid is better. lol

cHarley.......or anyone who knows........
1. What percentage of fuel (or general fuel amount) is there left in the tank when you are forced to switch over to reserve? It would be nice to know my range without having to test it myself.
2. Is there any harm of burning up a fuel pump if you run the bike out of fuel? Many modern cars have the fuel pump built into the fuel tank. The fuel keeps the pump cool, so when you run out of fuel, the pump could possibly overheat and burn up.
Thanks.

Depends on the petcock. I asked Pingel about mine, and they said like 3/4 gallon, but...I can't even go 20 miles once I switch to reserve. I think there's somethin wrong with my petcock anyway.
