fuel light question
good afternoon all, i have a 2006 fuel injected nightrain. fxstbi. this is my first fuel injected bike. i bought it used so i dont have the owners manual. i have the service manual, but i cant find any info on the fuel light. since this bike doesnt have reserve, i assume the fuel light comes on at some point when the fuel gets low. does anyone know at what fuel level (gallons) it comes on or what range of riding i have left once it does? thanks!!!

Sorry, I reversed that didn't I. It should illuminate at one gallon. Again, in theory. Mine is pretty accurate but I have read quite a spread of what other people see.
Personally I use the odometer primarily and use the fuel gauge and low gas light as second opinions.

Mine also has a miles left to empty option in the odometer display.
Does adding a Power Commander or other piggy backed fuel management affect the accuracy of gas mileage based features or readouts? I hadn't really thought of it until I read his post.

Most are so inaccurate hardly anyone trusts them to do more than look nice.
Adding a PC or any other fuel management add on system WILL screw up the 'miles to empty' feature, that is if it ever worked right in the first place.
The reason is easy to understand when you remember that the PC modifies the injector output, lengthening it in most cases. So the ECM is basing its mileage estimates on how much fuel it 'thinks' its putting into the engine. But with the PC making the injectors put in a little more every time. The gas tank IS going to go dry sometime before the ECM thinks it should.
A reasonable rule of thumb would be to refull the tank every 100 miles (it easier to calculate mileage with a 100 mile base) until your sure you understand how much mileage your really getting then adjust your refill mileage mark from there.
Ride Safe.

The light on my 07 Heritage goes on when I have .9 gallon left in the tank. As mentioned above, I use the odometer and fill up at 150 miles.
