    I was following a thread from a fellow inmate, on how to repair a sticky fuel gauge, only to find upon opening the tank top that my assembly is not the same as in that thread ( for a GSA). I remain with the faulty fuel gauge and ignorant on how to approach this repair. Anyone with experience, please share with me how to tackle this repair. The ride in the subject is a 2000 r 1150 gs. Thank you!

    To be honest, put a piece of black electrical tape over the RID fuel gauge, and just pay attention to your odometer. The fuel gauge is for entertainment purposes only.

    Two commons causes. 1) look at the top and bottom of the swipe. You should see a small black plastic tab that limits the movement of the arm. If the are missing the arm will get stuck at full or more common empty. 2) the swipe is not reading correctly. This is caused by a bad wire between the swipe and the connector or the the fellers are worn.
    The electrical problems can be fixed fairly easily if you are handy with a dvom and solder gun just be very careful not to break the white board.

    Not true, the gauge works reliably if the sender tracks are cleaned carefully with a Q tip soaked in contact cleaner each time the fuel filter is changed (they tend to build up with an oxide that comes from the fuel)
    The other thing that needs attention is the connector to the tank. BMW should have used Gold Plated pins & sockets there but instead just use Tin Plated ones. These must be clean and void of any oxide and then coated with dielectric grease to stop any further oxidation.

    I have serviced/repaired quite a few doing the above with great results.

    My gauge nevers reads full. The last bar never illuminates - no big deal for now - but do you think the above procedure will fix it once it's time for a fuel filter change?

    I did this to mine and it works much better now.

    As for ignoring the RID and only using the odometer- this is bullshit. My fuel economy varies from 25 mpg to almost 50 mpg, depending on my riding style and head winds. The odometer theory is shite. Even if the RID isn't perfect, at least it doesn't lie.
