This info is for U.S. model R3s. It could be different for other countries............

When the last bar on the fuel gauge starts flashing you have about .79 Gallons (3 liters) left in the tank.

The gauge then automatically changes to "Fuel Tripmeter" mode and begins from zero to count up the distance traveled from that point. You should then safely have about 30-40 miles (48-64km) to go until the tank is dry. NOTE: this depends on: how fast or aggressively you are riding, headwinds, etc.

Mine has come on when I have had 2 bars, 1 bar and a flashing bar. It also has switched off then come back on later on. Is this normal?

That's probably normal. Verify at your dealership....

From the exploded parts diagram of the gas tank it looks like the fuel level sensor is built into the fuel pump, which is located in the front part of the tank, so going up a long hill could make the light come on if there isn't a lot of fuel in the tank. Light should then go out when the road levels out or goes downhill.

The US owner's manual says it shouldn't come on until the bar starts flashing. Mine's only come on once so far - had reasons to top up earlier, the other times - but it was at the same time the bar started flashing. If you actually plan to rely on that, I'd have it checked. Might have it checked even if you don't plan to rely on it, you kind of never know with electrical glitches whether they'll stay minor or whether it might be a bad ground that could involve other components.

If it's a float gauge like most of them, yep it's normal (just as in any other vehicle) that acceleration, deceleration, leaning, climbing or descending can all change the level of the float and thus the fuel display. But, as far as I can tell from the manual, the reserve gauge and the flashing bar should be tied together.

Thanks for the info on the fuel gauge. I was wondering why at 1 bar it was only taking 2 gallons or so to fill up. That was equaling a 120 mile range.
