Fuel meter - .: XT660.com

Greetings from Cairo

My fuel meter has worked relatively well so far but now, all of a sudden the bars are dropping down twice as fast compared to what it used to be. And there's nothing wrong with the fuel consumption.

Has anyone else had this problem and if so, what was the reason?

And one more thing: If I stop the bike at let it stay put for some time, the bars in the fuel meter will rise back to normal, until I start riding again and then they drop down again almost immediately.

Mine was the same, I think the only thing it's good at is telling you when it's full and when it's empty . The rest varies as the fuel moves around or seems to. Ps the flashing empty alert and reserve fuel trip always was spot on on mine though never ran dry and most I dared on the fuel trip was 30miles and in got 23litres in .

wow you must have really leathered it Mac! i usually get 50+ from reserve, and on the two occasions that i've...err, 'tested' the reserve limit (ran out) i've had approx. 75 miles from reserve and only then have i managed to get 24L in!

Jami- yes, i agree with Mac-cos about the gauge, mine too is good at showing full and empty and not much in between. I usually ignore it and use the trip meter as a better guide, or just wait for the F-trip to come on. The fuel reserve on this bike is 7L so plenty of time to find a fuel stop f you're on a normal ride. I know its annoying that the gauge isn't much good, i think its because of the shape of the tank.

lol too many traffic light GPs plus I did often find that WOT was a good place to be when making progress

. Rrobably why I felt the need for the bigger brother.

Once you last bar starts flashing you have about 7 litres of fuel left, which is just less than a third of you tank. If you reset your trip when you filled up you have about half that distance available to you (eg if you have done 160 miles you can do a bit under 80 in reserve). To add a bit of safty margin I'd take 10 miles off that, and another 10 if you brim the tank when you fill it, ie 60 miles in reserve in this example.

In practice I could always guarantee getting 200 miles from a tank (even when getting only 40mpg due to stop/start and short runs). My lest efficient tankfull (39.88mpg) gives me a range of 202 miles to a non-brimmed tank.

The closest I got to running out was after 192 miles (about 40-50 on reserve) I only got 21l in the tank (not brimmed) which means I had about 2l (or nearly 20 miles) left.

Am I right in thinking that when you get down to one bar on the guage it will start flashing? The flashing indicates that you are on reserve which will give you between 30 to 50 miles depending on how you ride?

I too fill up at around the 150mark (done 5 now already!) but is handy to know the bikes limits in case of that 'in the wilderness and low on juice' scenario!

Thanks for info guys n gals.

Yes. Down to one bar, then the bar will start flashing and the F-trip will start counting up from zero.

I reckon you'd struggle to burn through the reserve capacity in less than 40 miles in normal use. Tripletom did try it with a fuel can on the back, and got 50 miles to dry, and I'm sure he won't mind me saying that he's not one to nurse it along to conserve fuel.

I hardly ever fill up before it starts flashing, and if I'm just commuting I'll usually run 20 miles or so into reserve before I even think about going for fuel - but then I know where the petrol stations are, and doing about 200 miles a week I spend enough time stood in them as it is without filling up more often than I have to

Hey Jami. Could it be the heat that is causing the issue?

uberthumper · # 9 16-11-10, 10:38

Mine seems to have got worse lately in exactly the same way...as you say, dropping down quickly while riding, then 'recovering' while parked up.

Even does it overnight, so it's not due to the fuel expanding when hot. Quite the opposite it seems.

I'd trust Osama Bin Laden before I trust my fuel gauge....

I can't agree with the others though, the only time it's right is when the bike is full!

I too have managed 70 miles on the F-Trip, but I use the trip like everyone else. I also fill her up at 150miles, normally get around �15 in the bike, depending on my riding, price of fuel and temp (always get more mpg in the cold).

With a quiet frugel ride (is that how you spell frugle/frugel/fruggle/slow!) I have managed 300 on a full tank, with some fumes to spare, moreover though around 250 is about right.

It's not just the Tenere, my XJR has a crap gauge too.......
