I never have had any luck with a fuel gauge on a bike. Throw in computer controls and then bhalewwieeeeee.

Good luck my friend.

I stopped relying on Harley gas gauges and mile to empty decades ago. I learn pretty quick how much I can get on a tankful in a particular bike by watching how much I'm putting in. Last year I ran my glide 250 miles and put in 5.8 gal   I knew on this particular bike 240 is a safe range for how I ride and I just pushed it a bit too far.

I think the gas gauge on my 16 SESG isn't working correctly. My gas light comes on at 175 to 185 miles, if I am on the freeway it doesn't come on until I hit the 200 to 205 mile mark. When the light comes on and I pull over to fill up at 180 miles I only put in 4.5 to 5 gallons in. So that means when my light comes on I have 1.5 gallons left. My wife's standard 13 street glide can go 220 miles regularly before needing gas. It is frustrating that at 175 miles my bike says I have 15 miles before I am empty and my wife's bike can go at least another 40 miles before her light comes on.

I have talked to 2 different Harley dealers and a Harley employee and they have all said the same thing, "that's how it is suppose to work". My old 04 the gas light would come on with a half gallon left, the new ones come on with 1.5 gallons left?  It doesn't seem right to me, with a 6 gallon tank my light comes on at the 175 mile mark which means I would be getting around 25 mpg. Anyone else have a issue similar to this?

Thanks

I filled up Friday morning and rode 198 miles (I don't believe I got it all the way full) I show 53 miles to go on the reserve and the gauge is showing under 1/4 but above the red, I guess I never really paid attention as to when the low fuel lamp came on, the owners manual is very vague on when the lamp should come on. As soon as the weather changes and I can get out for a few more miles I will update you on when mine comes on. I replaced a 2015 SGS with this 2016 SESG and I did notice I did not get as good as fuel mileage and the SGS, but I just assume because of the 110 motor verses the 103

Maybe it means you have 1.5 gallons left, but not necessarily.  How do you know you really started out with a full 6.0 gallons?  Before assuming too much, you might want to test the actual capacity of your tank.  Also, have you done controlled fuel consumption tests, filling the tank to a predefined level and then riding at least 100 miles before filling again to the same predefined level?  Simple math will tell you exactly what the consumption is in miles per gallon.  See if the real number is significantly different from the assumed number based on the miles to empty reading.

The low fuel light should come on at 1.0 gallons remaining per design.  Sadly Harley's quality levels are such that there has always been a large variation between design and actual, but that doesn't mean it can't be fixed.  Assuming the gauge itself is OK, tweaking the float arm of the tank sending unit can make the gauge read accurately, at least in the part of the range that's most important (1/2 to E).  Yes it's time consuming and can be a PITA, but it is possible.  Been there, done that on more than one bike.  Be thankful if your gauge reads lower than actual.  The one on my 2005 was the other way around and ran out of gas with the gauge still showing almost 1/4.  That one isn't just inconvenient, at the worst it can cause an accident if you run out in the wrong situation, or at the least a long push with a very heavy bike.

The service manager at the dealer I bought the bike from wanted me to keep a log of mileage the light comes on and how much gas I put it. He said he could bend the arm on the float to make the gauge read more accurate. Seeing as it is cold and salt covered roads I will start the log in the spring. One of the reasons I was thinking of switching to Dakota digital gauges was for a more accurate fuel gauge, when we put them in my wife's bike the fuel gauge read more accurate then the stock gauge. Everyone tells me I am nuts worrying about this but spending $36k on a bike I think it should be a little more accurate then that.

I fill the tank all the way to the bottom of the filler neck, sometimes a little into filler neck. I need to find a 6 gallon gas can so I can make sure my tank actually holds 6 gallons.

I had a similar problem on my '12 FXDWG when i swapped out the analog gauge for an LED version.  Had to resort to motorcycle algebra every time I filled up.  Could never seem to get it right but I read on other sites that there may be an adjustment needed/resistor installed to ensure the resistance is dialed down.  Much like LED lights needing a voltage regulator in order for them to work properly.  JMHO.
