My fuel gauge responds the same as yours.

I was distracted, and started riding one day without filling the fuel tank. I actually ran out of gas approximately 3 miles from the nearest pump. I rode about 250 miles on a full tank.

Our friends from Argentina report the fuel tank actually holds 14 liters, or 3.7 gallons, rather than the advertised 16 liters, or 4.2 gallons. The fuel pump in EFI bikes probably displaces a pint of fuel. Therefore, the actual fuel capacity of our U.S. bikes is probably 3.5 gallons.

To prevent overheating the fuel pump, it should be submersed in fuel. Therefore, it's best not to use the last 1/2 gallon of fuel. When the yellow light starts flashing, you probably have 1/2 gallon of fuel, of 35 miles of riding before you start to uncover the fuel pump.
