One comment I made in one of the forum threads, when I changed my 07 ECU to a 05 ECU is it was better on fuel, it never was as low as 13kms/L. I can get around 300kms on 15L of fuel.

What mods are on your bike, where is your CO set to. If you want to do a few checks we would need to move the question to the ASK KEV section so we do not hijack this thread.

Normally I do around 300-325 km on a full tank

Mostly on the big open (what do you call it? a-roads?) with a bit of city and off-road also.

thanks kev
I,ll fill the tank and go for a steady ride today, just to see if that makes a difference.
I,ll let you know the outcome.

Well i kept below 70mph, and after 46mls filled the tank again with 3lts.
I was a bit surprised to be honest. :017:

Unless my maths is wrong, that's about 70mpg - about what I am hoping to get from mine when I pick it up tomorrow.

Why are you surprised? Because of the big difference?

With the weather this time of year being as it is Not so nice, I generally am only pottering ( true you dont really potter:bricks: on an xt ) around riding back and too, to work. But still getting no less than 50 mpg. Usually I get nearer 60. :icon_cyclops:

Hi There isnt when you get your bike done on the Dyno then that will sort everything out from the fuel till the air? And ones it is done you van no play around with the setting or it was kind of useless getting it done? Iam talking abt fuel up and down changing trottle position etc...

well, i do about 112-115 miles before the fuel light goes on, so with 10 liters - about 2.2 galons(uk) of petrol i do about 115 miles - thats about 52.5 miles/galon. i ride in london, so i think that's not to bad in this traffic. i have the k&n air filter and i do about 10 miles more than with the original filter. on a xt 660r, 2007. will kevs fuel mod help me do more miles before refueling?

Standard XTX apart from a pair of CCC cans. Used for commuting each day, about 5 miles each way (yeah , I know I should use the bicycle, but the XT is SO MUCH FUN)
The fuel light first flickers on at 86 miles (for 4 times in a row it was exactly 86.4 miles), I fill up at 100 miles with 10 litres. that's 45mpg.

The last few weeks, now it's lighter and warmer, I take the long way home once a week, about 15 miles, and my fuel light is coming on at 96 miles and filling up at 110. So I'm getting the extra 10 mile ride for free petrol wise.

Getting 120 miles before the light comes on at the moment, well chuffed with that after the XJR that the XT replaced was doing 90 miles before reserve and the tank was 3 litres bigger!!!
