Fuel Capacity Meter/Gauge

Hi All,

I'm considering the GT as my next bike and I have a quick question about the fuel gauge. How does it display remaining fuel?

I know there's a system that estimates the remaining distance but is there an actual accurate fuel level indicator?

I currently ride a v-strom which uses the "5 bars method". Although the bars are not linear (5 bars = 22l, 4 bars = 14l, 3 bars = 10l etc) at least I know exactly how much is in the tank judging by the number of bars.

Thanks....

The GT has a fuel guage, similar to the one in a cage. It also has a warning light for reserve.

The fuel gauge is a long, vertical bar that goes down in small increments. Think of it like 10 or 12 small bars stacked on top of each other, with marks at 3/4, 1/2, and 1/4. It seems reasonably accurate in terms of the volume of fuel remaining, if not total mileage.

There is also a Miles Remaining countdown that is wildly inaccurate. When you first fill up it gives a good indication of miles remaining (say, 240 or so), then as the fuel is used up it stays high for a while then starts dropping slowly, then near the end starts dropping much faster.

So at 3/4 tank it will still say something like 210 miles remaining, at 1/2 tank you have 160 remaining, at 1/4 tank you have 90 remaining, then it starts dropping rapidly so that the last 60 miles remaining gets used up in 35-40 miles. But when the Miles Remaining gets to 0, you still have a full gallon "reserve" left.

I can usually count on a 240-mile tank (going into the reserve area), so I just reset the trip meter at every fill up. That seems to be much easier and much more accurate, although I do also monitor the fuel gauge to see if there is any significant variation (higher mileage at high altitudes, lower mileage at high speeds or into a headwind).

Having said all that, the fuel gauge is pretty much trivial once you start riding this bike. The power, handling, comfort, excellent amenities, and sheer fun factor far outweigh the minor things.

So go ride one and see for yourself.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Miles remaining

Ken,

I got a software upgrade to V11. It was part of the airbox upgrade to my 2006. One of the benefits is the miles to empty is now linear and accurate. The mpg is now accurate too.

Jeff,

My version 11 software hasn't changed the fuel gauge. It reads empty with 0 km to empty with at least 4l (about 1 gallon) left in the tank. I always ride at least 60km after the gauge is on empty and the count down is showing ---. This is how it has been for 27000km or since I bought it at about 1400km.

Interesting. Did v11 mess up your ESA settings?

I think I have an anomally here based on everyone else.

Fuel light comes on and miles to empty shows 45-47 miles to empty.
I get gas within 5-10 miles, each time I put between 5.2 and 5.3 gallons of gas in, my calculated average is usually 47+ mpg. So if I run to 0 miles to empty the tank should be empty??

What is the real tank capacity from the manual, it says 6.3 gallon, correct? or am I missing something

That does sound a bit odd. I've never gotten 47 mpg on my GT.

I'd strap a 1 gallon plastic gas can to the rack then ride the GT until the miles to go shows 0, then keep riding until it runs out. Then put in the gallon and find the nearest gas station to fill up. That way, you'd know for sure how far it will go and how much it will take.

Do you fill on the side stand, or center stand?

That matches what most of us are seeing. Here is my experience:

1. The fuel warning light illuminates when the remaining fuel indicator first touches the "top of the triangle", where the "triangle" is the tapered area at the very bottom of the fuel bar.

2. The miles to empty matches the current OBC miles per gallon. In other words, the triangle indicates that there is one gallon remaining. (There is actually more.)

3. When the remaining fuel indicator reaches the bottom (lowest tip) of the triangle, the miles to empty reads "---".

4. At this point, you still have some fuel left. I have ridden 15 miles past the point where the miles to empty read "---". I put 6.0 gallons in my tank at that point.

Someone posted a very scientific analysis in one of these forums (link??), where they ran their KGT to empty (not recommended) and determined that about 0.6 gallons remained when the miles to empty reads "---" My 15 miles after "---" and 6.0 gallon fill-up says that his calculation is reasonable, assuming some round-off errors.

My wife was watching television this past weekend ("20/20"). The report was about how many miles remain on your car when the fuel gauge reads empty. According to the report, Americans expect some "reserve" even when the gauge reads empty, Germans want to know the true fuel level. The reporter drove a Dodge Caravan past empty, and travelled over 20 miles.

See:
http://abcnews.go.com/2020/Stossel/S...3989000&page=1
http://tankonempty.com/


Here is a summary for my K1200GT. I assume that this matches other people's experience:

Fuel Capacity: 6.3 gallons

Warning Light Illuminates:
Appears after 4.7 gallons have been used. Approximately 1.6 gallons remain. Distance to Empty should match current OBC miles per gallon.

Distance to Empty reaches "---":
Appears after 5.7 gallons have been used. Approximately 0.6 gallons remain.

Center stand, drilling the fill nozzle is on the agenda.

Stange thing though,, my wife rides the Ducati a lot and gets 60+ mpg, when ever I ride it I'm lucky to get 40 mpg, Of course she is on the GT when I get 47+ (must be my tender kidneys )
