Getting a Grip on Fuel Range.....3.5Ltrs reserve or not?

Post by Aussie Dave » Sun Aug 06, 2017 11:44 am

Hi all,

On way home after today's breakfast jaunt down to Kingscliffe NSW (the Choiux Box Cafe) I got the pannick nanny warning 'low fuel' when I was at 357kms......

Ok ok, assume 3 ltrs x 18k/ltr displayed = 54kms safe......dash says 70kms.......yeah right.......411km safe, 427kms dreaming........so I know which one I'll believe :lol:

Get to servo at 385kms.......expecting 21ltr fill and it only takes 19.98ltrs (and not a drop more!).

So the av cons is accurate.....dash was telling me I was doing 19.1k/ltr prior to the fuel stop as I was being fuel wise on reserve....... and the calculation at the pump agrees.(385/20=19.2k/ltr).

But the dash also was still telling me I had 70kms range..........hmmmmm......takes a while to update.....

Gotta watch that...... ;)

Psst, Gotta watch the Moto GP......on at 9.30pm.......been three boring weeks without a fix....... :lol:

That low fuel silent scream by the display is very attention getting (got mine enroute home from from the garage when I bought mine) Still wary of any electronic guess machine, if in doubt, do the shake and listen :)
The motogp race is interesting ;)

On Saturday i did a ride with a mate on his 1299S from home to Pio Pio back to home via a back road, it was a quick ride both ways (scrubbing in a new rear) my fuel warning came on at 264 Ks, i have the larger rear 40 sprocket. I haven't filled up yet, but will come back will how much she takes. (I'm picking 18-19 litres) Oh my mate on his 1299S filled up in Pio Pio, its nearly a tank each way for him when the speeds get up. I once did 400Ks, 30K on reserve, and i put 21 litres in, had the wife on the back too, it was a leisurely ride.

Interesting thread. I haven't been able to make any sense out of my fuel gauge yet but I haven't really applied myself to it either. I guess filling it up ten bleeding fuel out of the tank and seeing how what amount of fuel corresponded to what bars would do it but that's a hell of a PIA :D

nah, I just wait till I get a reserve warning just as I approach a fuel station, then fill it.

I've noticed it takes 18-19Ltrs to get to reserve from full ...... I haven't had the urge to lift the tank off when it is nearly empty and drain the dreggs out and measure just enough to get me to the fuel pump to see what it will take to fill it up from almost empty........but I'm now confident there is more than 3 Ltrs once the warning fires up on screen (KTM claim 3.5Ltr reserve).......of course range is so variable depending on load/speed/wind/fuel quality..etc etc.... :roll:.......but I never trust any 'Range to Empty' display.... ;)

I've never been comfortable with range-to-empty gauges either. What sort of distances do you have between fuel stations in your part of OZ?

They can average 50miles/80kms even on relatively main roads in the more rural parts of West Texas. If you like to explore the back roads, they can be far less frequent than that.

Well, I ran mine out of fuel 500 ft from my garage door at 249.7 miles...I will not do it again but it helps me keep everything in perspective.
I was trying to get home because it was very hot that day and wanted to get my wife home...the positive is that I am comfy riding with the blink warning as long as it is anything but zero

Always handy to carry a portable bike pusher on these occasions ;)

Cheers Allan.......fuel stations can be hundreds of kms apart in the sparsley populated zones over the other side of the 'Great Dividing Range'.......from knowledge or planning (map)...... I'll only run near to max range when I know there are fuel stops before the one I think I can make .....just in case I get it wrong or decide to chicken out.......reminds me of one trip, long ago.... :roll: ....uh-oh here he goes.... :lol:

We were travelling home from the Aus GP at philip Island (as it was known in those two stroke days)........and out in the middle of nowhere in country Victoria I got an unexpected low fuel warning lamp at some ridiculously low mileage (FZR1000 could do 19k/l or 54UK mpg on tour and carried 22ltrs usable)......I was in trouble......no plan B......only 2 ltrs of reserve fuel - and I was already well into that........unfamiliar territory...not happy at all......phew, over the border, round the corner and there was a fuel station :D .......but why was I getting less than 10k/ltr on that tank? - did I have a bike problem??.......nah, turned out to be crook fuel (it smelt awful and the fuel attendant said there was bad fuel were we had just come from).......back to 19k/ltr for the rest of the journey....... I love fuel gauges for that reason (gives earlier warning)....... but a trip meter that auto-resets to zero when reserve is triggered would be really helpful - the av cons readout is a huge plus.... ;)

Had to pit for fuel yesterday.......took 21.13Ltrs for 380kms.......range-O-meter claimed 30kms to go....Ha Ha....I reckon more like 15kms left.....and when I stopped at traffic lights facing uphill the rangeOmeter dropped to zero :o

So that's all good experience and familarity....all part of the deal with a new bike from a new manufacturer ;).

Put 90mls of Valvoline injector cleaner in for this morning's squirt in the hills and didn't that liven up the throttle....... :lol: .......musta cleaned out some carbon deposits.....pity I wasn't at my best and couldn't fully enjoy the extra zing..... :lol:......had a beaut ride anyway...

After doing 265 fast Ks, and the low warning fuel light coming on as i got home, i put 18.5 litres in today. i didn't take any notice of Ks left to empty, but id say i had 4.5 litres left or aprox 75ks. My 1290R said the tank held 18 litres, well from bone dry to full it took 18.8 litres. so KTM actually have larger tanks than what are stated.

Cheers DNZ....

I've been thinking same for Gt......but yet to drain tank and add a measured amount to cover short ride to fuel servo an see what a fill to the brim (bottom edge of filler neck) should be.......handy to know so a ride isn't spoilt by worrying needlessly about range to empty....there are some servo's I'd rather ride past than risk buying a tank of bad fuel.

Yet to take tank off - so I'm still wondering how the fuel flows to the pump side in right turns....not that I ever want to run the pump dry.....just want to know it's limits.. ;)

9,550kms - nearly up for my next oil change, rain storms cleared, wonder where I'll ride to this weekend..... decisions, decisions, :roll:. :lol:

Ive recently done my 7500 K oil change, i went for 10W40 motul 300, next change for me 15,000 I'm confident quality oil can do 7500Ks, especially when they say 15,000 between oil changes, oil has come along way. I've now done 11,300, and i reckon the suspension just keeps getting better. Oh PS Dave, i ordered the same hand guards as yours, they arived, but i couldn't fit them as you (i) had to order the bolt set that holds and locks them in place separately :x

Hi to myself in the 'shaky Isles'.... ;)

Can't recall any extra's so maybe the 'switched on' sheila at KTM Central knew to order them without mentioning it.. 8-) ...

By he way, don't bother using the spacers (they aren't bar-end weights).... the Acerbis guards fit perfectly without any spacers......my Dual Road's came in a wrap like this.....err pic quality not the best.....sorry.. :oops: .........it is surprising how much weight comes out from inside the oem bars.....but the Acerbis seems to counteract their absence with its own weight and shape..... 8-)
