Fuel economy
 

hey everyone.This might sound like a stupid question but i just want to know how many Kms some of you guys get out of your bikes till your on reserve and then how many Kms you get on reserve? i only ask because my brothers Honda VTR250 and my dads Italian scooter(dont know how to spell it as there arent many in Aus http://www.xt660.com/images/icons/icon11.gif) kill my Xt660x on the long distance rides. I know the XT660x has only got a small tank compared to the bikes above but just want the reassurance that my economy is alright.I havegot about 270kms until reserve and the most i wanted to push it on reserve was 30kms.Any feed back would be great! http://www.xt660.com/images/icons/icon14.gif

cheers Richo

I have owned a 04 XTX & own a 07 XTX they both have simular reserve level times. The fuel light flashes on/off around 210kms mark & stays on at 230kms, fuel runs out around 310kms on the open road & around town I get to 200kms & then 300kms then I walk.

normally get around 140-150 miles then the light comes on and the most ive done with the light on is 30miles as i didnt wanna have to push the bike:icon_burnout[1]:

Mine around 100 km until the light, then around 43 km until it dies. Yeah, 10l/100km. But I usually push it all the time. And the bike is open like a french cheese and have PCIII fitted.

I get about 200km then the light comes on and I have DNA stage 2 + de-screened air filter, cans and a PC3

I get 80-100 miles (120-150km) before the light goes on when commuting, and about 120-130 when riding the lanes.

I usually fit about 10-12L of fuel once it's on reserve, which means it must go on quite early.

I have been looking at everyones fuel range & have been scratching my head to why mine is different till reserve & have just remembered my tank has been drilled to allow a higher fuel level. I had totally forgotten about it..

I have four holes drilled in airbox, snorkel removed, DNA stage I and stage II filters, OTR 2in1 pipes + silencer, db killer removed, no catalytic converter in link pipe, nology hotwire cable, iridiumx spark, PCIII, O2 eliminator and lambda removed.

But from all of this, I think a PCIII map that crazy german have pre-programmed for me is the biggest fuel eater. I plan on connecting the PCIII to a PC to have the map saved and posted on forum for investigation. I would like to see can I have a same or nearly the same performance without such crazy fuel consumption (sometimes even above 10l/100km!!).

I had similar to the above +, a 102mm big bore with 11:1 high compression piston, stage 1 hot cam, +2mm throttle body & I got 20kms/L. I now run with the standard cam as it is far better with all the above & now get over 20kms/L on the open road.

When I converted my bike from a 07 ECU with O2 sensor to a 05 ECU with no O2 sensor my fuel consumption improved greatly, I did pass this comment on one of the past threads.

And do you think just by removing the lambda sensor and fitting the O2 connector eliminator (without ECU swap or anything else) could improve the fuel range?

I'm already riding around town small distances and I expected the light yesterday but it haven't turned on yet. It might just be a feeling, I must do a proper test will full tank and trip clock reset to see is there any difference at all.

No I don't, mine was the same with the O2 sensor connected or disconnected.

I do feel there is something wrong with the 07 ECU's as my 10 ECU was heavy on fuel & all I did was fit the 05 00 ECU & my fuel consumption improved greatly.

i get 210km on tank then reserve goes on.
In theory you have 5 litrs left in tank, so you can assume to go half more of km you did, so approx another 100km. If you want to find out exactly how far you can go, take some fuel with in 2lt bottle, and ride it till it dies.
I have seen it depends on your driving style also, if i ride it hard and higher revs, you obviously get less. reserve will go on at about 190km.
I have Stage 1 and 2 filters, no other major mods.

Since I changed the tyres to Conti TKC80 I get 185 miles and the light comes on. Never tried to push reserve too far (bit of a whimp). Only mod is snorkel taken out, fueling set at 19 and a K&N filter. Average to hard riding.

Sorry forgot about the cans, ditched the standard pipes.

Thanks everyone for your input. Just came back from a cruise with my dad from Adelaide to Canberra for a holiday and i worked out i get about 170km before the light comes on when doing long distance driving and about 230 when im driving around town.Its interesting to see the different efficiencies with the different add ons to the bikes
