False reading of Fuel guage

Hello,the 5 bars on my adv model seems to provide false reading. according to the manual when both the last bar as well as the fuel pump icon on the right hand side blink, there should be a little over 2.6 US qts left. however, I am never able to fill in more than 4.3G if I stop to fill in right as it starts blinking. which tells me false reading. I saw one older post on this topic but not much traction on it since. anyone else having similar problem?

you're sure you're not reading this on the sidestand right? The bike has to be upright for it to be correctly reading the fuel.

I usually have to put in 4.6 or 4.8 gallons in. Mines fine.

so if my math is right, mines is off roughly by about 0.5 gallon on the read. (5.3g tank). I can live with it, but kind of annoyed and not sure why it happens on a new bike.

None of the OEM fuel gauges are all that accurate. The wisest thing to track your fuel use is to set the trip meter to zero each time you fill up. I would advise looking for a gas station at around 225 miles. That will give you roughly 50 or so miles to find a gas station, based on an average of 50 mpg. You will prolly get more miles but just to be safe. I have been averaging close to 60 mpg but yours may vary of course.

I've posted a few times that I have this problem too - took it to the dealer who couldn't see anything obviously wrong. If I fill up when the little fuel symbol starts blinking (while riding, not off the side stand) I never put in more than 3.75 gallons, and if I wait until the last solid bar also starts to blink, I put in about 4.25 gallons on a 5.3 gallon tank, same as you. For those keeping score at home, that's FOUR quarts of fuel left in the tank on the last blinking bar, versus 2.6!

So now, I just ignore the first blinking fuel symbol and know that when the bar starts blinking I'm down to a gallon. Though if I were to ride somewhere desolate with 75+ miles between gas stations I'd respect that first blinking light a bit more :P

I considered taking it back to the dealer to demand a warranty repair, but I'm not sure this is a problem serious enough to fix - sure it may be covered (or not), but it'd require removing the tank, checking the fuel float, maybe a bunch of other things, etc., and I'd lose a few days or a week of riding time for no good reason.

I use miles as my primary fuel remaining indicator as well. A habit developed riding long before motorcycles had fuel guages, but a practice I still find works well. Not that I don't appreciate the fuel guage, it's a useful secondary indicator.

My experience so far, over 2600 miles, has been typical averages of 65-67 mpg. At first I couldn't believe it, but repeated checks continue to confirm. This yields an absolute range of ~340 miles! Recently waited till 270 miles to refuel and 4.2 gal filled it up, consistent with the above mpg figure.

Now 65-67 mpg is certainly due in part to my riding style (OK, I'm slow). Even then, a stretch that consisted largely of 75 mph into what must have been a 30 mph head wind yielded 55+ mpg. Bottom line; this is one efficient engine.
