    Fuel Guage not registering properly.

    I just bought a 2016 Trophy, with 1975 miles on it.  I am pretty sure that it sat still for many months.  Here is my issue:  the fuel guage will not register as full.  Even after riding for a few miles to let the computer "adjust" to the new level, it still only reads as 3/4 full.  Additionally, the low fuel warning light comes on with the 60-mile to empty message.  But then the bike only takes 2.8 gallons to fill.

    Has anyone else had this issue?  Is there a float-valve that could be sticking?  Does it sound like a computer problem?  Any input woild be welcome.

    Cheers!

    Jim

    You've already discovered that after refuelling it can take a couple of minutes of riding
    before the level updates on the gauge, which is normal, but it seems likely from your description
    that the Fuel Level Sender is faulty. ( Part Number T2400248, Approx. GBP £84.00 )

    Other Forum Members have had Fuel Gauge reading errors that were cured with a new Sender.

    See if you can get it changed under Warranty if you have Warranty.

    When changed it will also need a new Seal ( T2401225 - Approx GBP £8.00 ).

    To replace the Fuel Level Sender the Tank has to be drained, removed from the bike,
    inverted, and then it's simply 4 fixing screws to undo, withdraw the Sender, discard the Seal,
    then fit the new Sender with a new Seal, tightening the screws to 5Nm, and refitting the Tank.

    See this Topic for guidance on removing the Fuel Tank :

    HOW TO: Remove Fuel Tank and change Air Filter.

    Before I'd spend $$$, I'd go through a few refills.  Keep in mind your mileage and perhaps after the Fuel Level Sender is "exercised" a bit it may loosen up and start registering a bit better.  Of course, I'm cheap and generally use my trip odometer as much as my gauge when refilling.

    Jim; Are you doing a "Trip Reset" after refuelling?  What you are describing I have experienced if I had not done a reset.

    The issue definitely is not related to resetting the trip-meter.

    The system is only registering 4 gallons in the tank.  Yesterday, I filled the tank, then watched it slowly count down four gallons used and showing the tank completely empty.  "0" miles left to the tank.  I then rode it another 100+ miles "on empty", watching the "miles from last fill-up" and "fuel used" icons.  The system simply never shows a full tank of gas, only registers 4 gallons, and sets the "empty level" based on those 4 gallons.

    I have put Chevron Techron in my tank and the fuel gage was not reading right after that but after that it went back to reading right.
    I'm not sure what maybe making your gage to read wrong but try the Techron additive to see if it loosen the mechanism up.

    Good idea, I'd try that too.

    When I replaced the fuel filter on mine I noticed that removal of that whole assembly were fairly tight through the hole, maybe a previous owner yanked on it, bending the float arm??

    There is no fuel arm. The sender is a long cylindrical tube. A float slides up and down in concert with the fuel level inside the tube.  Ohm readings on the sender should be linear from 13.4 ohms +-  Full tank, to 103.5 ohms +- Empty tank.  Your readings may vary slightly.
