Fuel gauge

[Kwikasfuki]

I believe the tank capacity is 22 litres. Once my gauge shows "E" (just before the petrol pump symbol flashes), I tend to do another 20 miles and fill up. I've noticed whilst filling up that the tank reaches capacity at 14.5 litres, meaning there is another 7.5 litres lurking somewhere. Are the gauges that inaccurate? Today I'm going to wait till the pump symbol flashes and see what capacity is left.

Hmm i get a whole other reading...generally my fill signal comes on with 40 miles range left in the tank which is roughly 4 litres...i generaly get 17.5-18.5l in the tank if i fill when the signal comes on, i have ridden 20 or so miels before filling up, and put 19.5 in the tank...that being said i do tend to brim the tank

As a rule on any bike i have ever owned the fuel gauge serves as a rough guide only, i don't like to drain the tank unless i can really help it and will fuel up when it the chance presents it self, as fgar as i can tell the GTR manages 8-10 miles per litre depending on how hard i am riding it, but with only 2.5k on the clocks i expect it to improve marginally when the engine finally loosens up and is properly run in

If I brim the tank (and I only do that if I have a journey immediately ahead of me) I can get another ~3 litres in. I'm wondering if the ECU estimates the range as well based on your driving style. I also have a PC-V fitted and I'm sure I read somewhere that it can lead to inaccurate readings.

As your current fuel consumption is constantly changing, which also effects the average too, on any given tank of petrol there is no set point effectively of 'range left', as you say riding style may effect this greatly......bimbling along 40 miles left could be 3ltrs, whereas if you are 'making progress' ::) then 40 miles left could be 5-6ltrs. You woudl think then that the fuel warning light would come on at a preset point in the tank? i.e. 5 ltrs ...but again this can be subjective...inclination of the bike/outside temp etc etc, so all in all i don't think its thats easy to be very accurate at all in estimating range/ litres left. With regards to adding a PC-V, as long as the sensors used (to estimate range....) on the bike monitor road speed, throttle opening and estimated fill level then it doesn't matter what you have fitted, it should not effect the tank fill/range readings

Maybe I need to stick a jerry can in my pannier and see how far I can get on one tank

It states in the handbook that the warning lights come on when you are down to 4l.

I nearly always wait until the warning lights come on and then find the nearest garage and squeeze in as much fuel as possible which involves a lot of trickle filling when it gets close to full.

If I fill up within a few miles then the bike takes about £25 worth which is about 18L so I would say the warning light is a good indicator that you are down to 4L but dont know how much off that can be used before you have to get off and walk 20L is the most I have put in.

How far the 4L will take you depends on how you ride

Flashing "low fuel" tends to come on around 190-195 miles on mine, I will generally go another 10-20 miles before filling up, and usually fit 18.5 to 19l in. 

I believe the tank capacity is quoted at 23l.

Someone in the USA did the "full jerry can strapped to the back" test.
He reported that ***LOW FUEL*** started at 185 miles and he made it to 235 before she conked <smirk> out.
Even if you do conk out the fuel pump is in the tank and therefore is self-priming.
You people with the 2010- get the added joy of being switched to "miser-mode" so may even manage a little further.

Now, who will be the first person on here to push the limits and run the bike dry? <LOL>

I rarely get to see the ***LOW FUEL*** these days as I fill up daily after 120 miles.
The main reason for that is that petrol is lots cheaper in Essex than in Crawley!

Our FJR starts a mileage count when the fuel warning light comes on. Our GS continues to tell us the estimated range (as do both our cars).

I'd love to know who the genius was at Kawasaki who decided that once I was low on fuel the bike would flash ***LOW FUEL*** at me, removing the range, showing me the gear I'm in only if I happen to be looking at it when it flashes on and removing access to any of the other useful information in the top of the display.

Hi

While I was out last Sunday with FH going down to Bognor I put the bike into full Economy mode (2010 version) as it was going to be a leisurely ride.

The complete round trip from home to FH, Bognor and back home again was something like 226 miles which I managed on one tank of fuel  :) the low fuel light come on at 214 miles but with only 12 miles to I wasn't too worried.

With the low fuel warning light on, I managed to fill up to 18l which means the tank has 4l. So as long as I can find a garage within 40 miles of when the warning comes on I should be ok.

I dont like running the tank too low deliberately in case it sucks any shit into the engine thingy!

Hi

Isn't that why there are fuel filters fitted ???

I would strongly suspect that if there was any muck in the tank it wouldn't get much chance to to stay settled for any length of time due to a) the very act of filling up the tank and b) the amount of movement on a bike

Kind regards

On the last trip to Germany (autobahn), where I was driving with almost constant speed of 150-170km / h, I drove around. 18-20 km / l. When E indicator showed the first time I had typically traveled 360km. It fits nicely with the 4L is left in the tank. Several times I actually provoked the bike and continue to provide 50-60km until the next refueling. There is no great difference whether I run in the rain, headwind or side bags fitted. Large petrol consumption arises clearly when I throw up the pace of approx. 190-200km / h. Then drop it very quickly down to below 15km / l or less. Generally, it is my view the ECU measurement and display is very correct and true.

It's that poxy how many miles you got left gauge that annoys me a bit. Never seems to make it's mind up.
