Low Fuel Light

Riding home today on my new EFI Bonnie, the fuel warning light came on with 95 miles on the trip meter. Then it went off. Then it came back on again, and then it went off. I'm just wondering if this is normal or does the light usually just come on and stay on? Also, what mileage are you guys getting before the light comes on?

The light on my Thruxton is way inconsistant. Sometimes 112, sometimes 128. I ignore it.

I'm sure the low fuel light is a rudimentary device comparitively. The gas sloshes around so much in the tank from leaning, stopping or going my low fuel light does that too. My best recommendation is to get a good idea of the mpg for your various driving styles (i.e. aggressive, normal and easy) and then you'll know much better than the idiot light. I've found that fuel mileage only varies so much unless something wild is happening. The benefits also extend to that if you notice a substantial drop in fuel mileage, there is most likely a problem somewhere.

I have the exact same model... 95-105 was very typical for me for the first 500 miles. You can "flirt" with the light for about 15 miles at highway speeds by giving it some quick on and off throttle (I guess it redistributes the gas to the left side where the petcock is) but once its on and stays on you have anywhere from 40-60 miles left by my experience. Once I reached 1000 miles or so I routinely get 115-120 miles before I start the tango with the fuel light.

(95% of my driving is highway commuting)

Ive got 3000 miles on mine, Ijust put gas in at 100 miles for a while, that made it easy to do the math. according to my numbers the light stays on constant at about 3.5 gallons

I don't have an EFI Bonnie, but my experience of fuel lights on bikes has been much the same as yours. They're about as much use as a chocolate teapot. You're better off using the trip meter as a fuel gauge. It's a shame you don't get reserve taps on EFI bikes, for good reason I know, but at least you get a reliable warning that you're getting low on fuel.

Fuel light woes

Hi Dan, I was going to abreviate your whole name to STD then thought better of it

I get about 97 -105 average on my 08EFI, but I mostly ride on my daily commute which is just 10 miles each way.

On the odd occasion when I have gone out for a much longer ride I get 120 -140 miles before the light comes on.

As such I guess our bikes are pretty fuel inefficiant when cold, so in order to get better fuel economy we should ride more

I would guess that the light works off of a level sensor, and a bike is seldom level in normal use. As others have said, accelerating, braking and leaning will all have an effect on the fuel level.

I do find that cruising along a relatively straight road at a constant speed, the light will come on sooner and stay on sooner than if I am hooning around town.

ps I am seeing the light first come on at about 110, and then it's intermittent up until about 125 when it comes on solid.

Ditto

At least there are no annoying beeps emitted, unlike on my car!
