Fuel float calibration

[Bear]

Is there a way to adjust the calibration of the float (not the nasty strip) that drives my fuel gauge? The bike is a 2010 R1200GS. The gauge seems to read two or three litres low as extrapolating the tank capacity from the distance travelled, the range alleged to empty and the amount of fuel needed to fill up gives a fairly consistent 18 litres.

Try bending the float arm but that's about all you can do. You could also drain the tank then add fuel by the litre until the float just starts to move. Then you'll know exactly how long you have before it runs bone dry after the gauge reads zero.

Ask your stealer,

There may be an algorythm / adjustment for setting your base line figure

The dealer who supplied the bike reckoned there was no calibration procedure. The documentation for the GS-911 details the procedure for the fuel strip but not for a float.

The best way to handle fuel related anxiety is to get a GSA, it won't make it go away but it will happen slightly less frequently.

Interesting

I know its possible on cars,


1. With the engine off, insert the key and press down the start/stop button twice. The date and outside temperature should appear.
Hold down the km/miles reset button. A warning triangle appears first. Keep holding the button until menu 1 appears.
2. Press the button sequentially until postion 19 appears.
3. Wait a second or two, until code -- appears. Without hesitation (otherwise the -- disappears) press the button again until you reach the calculated code, which is the sum of the last five digits of your VIN.
4. Now wait: "unlocked" will appear and the menu will go back to position 1.
5. Now toggle through to position 20.
6. Once you get there you can adjust the default value of 1000. I adjusted to 1090 as I calculated that the actual fuel consumption was approximately 9% higher than predicted by the on board computer.
7. Now go back to menu 19 to lock the menus again by pressing the button
8. Remove the ignition key.

so why not on bikes... or is the dealer trying to keep it as a black box item

( I may be wrong & it may not be possible on the GS, but it does seem strange )

very useful on a bike site well done

Some people really do go that extra mile to troll lol ....

i'm more than aware it was an adjustment for a car it was to show adjustments to supposed fixed values can be changed if you know where to look ...

Sort of. But because you hardly have to worry about fuel it’s all too easy to catch yourself out. Then that mega size fuel tank suddenly isn’t quite as clever as you’d thought.

Not to mention the shite fuel strip on some models.
