fuel mode

[Andy]

Eco Mode was the Japanese response to customer feedback on tank range on Mk I GTR 1400 rather than making it bigger. They've automated Eco Mode on 2012 ZZR 1400

But there's also a useful improvement in fuel consumption, made by automating the 'Economy' switch found on the 1400GTR. This advances the ignition timing significantly when engine loads are light (most of the time with a motor this powerful), and with other changes to the engine management has made the ZZR1400 up to 20 per cent more fuel efficient, although most of the time an owner would expect to see an 8 per cent advantage over the outgoing model.

One day I'm going to run my bike dry. I've done 20 miles on the flashing low fuel warning, and only manage to fill up to 19l (and that's 19l with overfill).

Why bother? 
The warning is supposed to come on with 4l left.
Your fuel usage can be quite different depending on how you ride.
Low gear and high revs => lower milage, high gear and low revs => more economical.
Going uphill also has an influence and going into or with the wind will make a difference too.
So even if you manage to get 270 miles out of a tank one day another day it may be only 220 or even less if you really cane it or only ride in city traffic.

He's just talking about "testing" the reserve range. The miles remaining is quite accurate but disapears with the anoying low fuel warning  Seemed quite acurate when I ran out (with a spare can...)

Aye, I want to know what the reserve level actually is. I don't trust the range reading. One sec its telling me i've 150+ miles and the next 50 miles.

No bigger tank, juSt slight overfill.

I always play the reserve roulette - only let me down when I forgot I was running at 110-120 miles missed target petrol station by mile and half, reserve won't run out to 40 to 50 miles at those speeds.

On all 3 GTR's low fuel (reserve) comes on with 40 miles on the range - and it's pretty accurate as long as your riding economically. ~80-90mph.

Auto Eco mode - are you sure?  2011 ZX10R has the same Eco mode indicator as the GTR when riding economically.  But not switchable.  When I'm not being a twat, I can get 42-43 mpg out of the 10, but I wouldn't't say it's a auto-Eco. Mode.

Obviously the computer calculates how far you would get if you carry on like you are running at the moment. The less petrol you have left the bigger the difference. If you look at the current mpg readouts you will notice that it may show 30 or even less one moment (i.e. you accelerate in a low gear)  and maybe 80 shortly after (engine idles while travelling downhill at 80 mph). So if you have just over 4 litres of petrol left and you shut the throttle at high speed it may calculate you can travel 80 or more miles while in the other extreme (low gear and lots of throttle going uphill) it will say, 'you'll be out of fuel in less than 25 miles!'
But you will find that the low fuel warning always comes on when the sensor tells the computer that you have only 4l of fuel left. In my experience that will get you anywhere between 40 and 50 miles on the open road and maybe 30 in city traffic.
In other words it's time to find a gas station within the next half hour or so.
