Default Question from new member

Hello Everyone,
New member with 2011 Ultra Classic. That the last owner has converted to Street Glide CVO tank/paint and all. The issue I have is that the tank only takes a couple gallon of gas and then is full, also reads full on both gas gauges the led on the tank and the original in the fairing. Any ideas??

Thank you in advance...
John

Hello and welcome.
Are you saying that the tank might have been "chopped"? I'm not a bike mechanic, but my thought would be to either drain or use the fuel in the tank and look inside with a flashlight and see if its been altered for some reason. If so, might consider replacing the tank.
With only a couple gallons, you might as well be on a sportster.

My idea is, the tank is full. 6 gallon tank, that usually takes 5-5.2 on empty, stop at station with half a tank or a little under, it holds 2-2.4 gallons, and is full, so there's 2 gallons, my idea is the tank is full and you are stopping to get gas around half full?


Am I right, and if so what prize do I win, because I know this has to be a test, right?

If you ride it longer, it will need more gas.

Step 1: Next time you fill up, zero the trip odometer.
Step 2: When the gauge tells you to fill up, take note of the miles and figure out what you're getting per gallon you put back in.
Step 3: Put electrical tape over the gas gauge.
Step 4: Ride till you use almost all of the 6 gallons and fill up.
Repeat until winter.

Fill the tank, carry a spare bottle / jug of fuel with you and ride about 200 miles. If you run out, use the spare fuel. If you don't, fill up and see how much you used. As mentioned, set your trip odometer to 0 when you fill up so you can calculate your fuel mileage.

Fuel gauges on Harleys are known to be inaccurate, buy not by that much.

A factory Ultra Classic tank will not have a LED fuel gauge on the tank, only the fuel gauge in the fairing. There may be a Road King tank on there.

I carry a Reda gas container, designed for Harley hard saddlebags. Unless the motor has been heavily modified you should get about 40 miles per gallon on average??? Ride 200 miles, fill up and calculate MPG then you will know what to expect. Harley gas gauges are notorious for not being accurate.

Sorry everyone maybe I wasn't totally clear on my situation, let's try again. I bought a 2011 Ultra Classic, the previous owner has bought a tank installed and painted it to look like a CVO Street Glide. That tank has a led fuel gauge and I have the original analog gauge in the fairing. When both say I am running very low and the analog low fuel lights up and i go to fuel up, i am only able to squeeze in a couple of gallons and it is over flowing.
Having said this carrying some extra fuel and setting the trip computer then running till empty seem like a great idea, maybe the sending unit is out of calibration.
