XT600 MPG - Your figures please.

**tedmagnum** · #1 24th December 2007

OK, miles per litre but you know what i mean

Im currently getting near exactly 10 miles per litre (16km per Litre) whilst travelling in Argentina on the smoother clear roads with a fully laden bike.

This is travelling at 60-65mph (100-110 kmph)

It uses marginally more with the wind or higher speed and less when im chilling on the bad roads etc

Out of interest, what are your XT600's doing ????

**Martynbiker** · #2 24th December 2007

17k per L on an XT600 1989 2KF mostly offroad n mountains. The only load is a 22 stone rider plus tools!

Just to add to my post here, just been for a 160km jaunt into the Mountains today (Xmas Day) 120km offroad and 42km tarmac, final figures Fuel used 7.86 Litres which is by my reckoning 20.93Km to the Litre or 94.63Km or 59.1 Miles per Gallon Im well chuffed!

Hello, y'all!! I got an average of 22/23km on a liter fuel, on backroads. On highway use a little less(1:20). Average speed is: backroads 80/90kmph, highway 110/120kmph. This all even with a K&N airfilter and a CRD-exhaust. My weight is 95kg, I run panniers on my bike(H&B). Hope you can use this info. Greetings, Hans van Langen.

worst ever: 15 km/l - best ever: 28 km/l!! old 34L model. 1985.

**greynomads** · #5 26th December 2007

XT600Z 3AJ model, 2-up and very heavily laden - average around South America has been 24 km/litre with a worst of 20 on gravel mountain roads in Bolivia and a best of 28 with the wind behind us. Maximum speed is usually 70 - 80 kph.

hmmmmmmmmmmmmm

Why is my economy so bad !!

My bike is a 2003 with only 6000 miles. Well services and smooth runner.

I usually cruise at 100-110 Kph.

You guys with better economy. What speeds do you ride at ??

Took me a year of screwing around

Its easy really.. that throttle is a tap, the more you open it, the faster the fuel flows, also don't put it in too high a gear.... I hardly ever get into 5th gear unless its tarmac and quick blasts of 100-110kmh.
But get used to keeping that throttle closed down a bit more and use the gears properly (I'm not trying to say you don't know how to ride, just don't over rev and don't Labour the engine and she will reward you)
i stick to about 90-95kmh about 50-55mph, got used to that speed in the USA it also suits the XT and my pocket!

Normally a Dyno-Jet kit (or similar) really can make a difference, not only in performance but in economy. Opening up the air box and using a performance
Needle is the key to it. Seems counter-intuitive, but a well set up bike with a Dyno-Jet kit can achieve better fuel economy than stock AND perform better in the bargain.

The trade off is you'll be doing more frequent air cleaner servicing, which is no big deal at all IMO and well worth the trade off.

Took me a year of screwing around with every possible jetting combination known to man to figure this one out. Just because the MAIN jet is bigger does not necessarily mean you're MPG will go down. Please don't ask me to explain this one!

I understand jetting and tuning as much as anyone...

I set up a perfect fuel/air mixture back home in the UK with my Quill can (road legal) using an exhaust diasgnosics guage at my dealership.

I probably ride to fast for the weight im carrying.

You may not agree Patrick, but Yamaha really DO know what they are doing with the Jetting on their Bikes. Every Biker I have ever spoken to who has \fiddled with jets and needle settings on his XT has as regretted the decision, as you said above IT TOOK YOU A YEAR, and i KNOW from your posts you were not the last in line when brains were handed out.

SO Unless you have a Rolling Road Dynanometer set-up in your Garage, and lets face it thats gonna be very few of us...... just fitting a Dyno-Jet kit can be worse than useless. each engine is different, they really should be set up on a RRD. what makes you think that in your garage at home with a Bottle of Molson in One hand and a screwdriver in the other you can do better than a factory that spent hundreds of thousands on R&D?

When you guys check your miles/Kms are you using the trip meter on the speedo or using a GPS. I guess the GPS will be more acurate but dont know how much difference it will make to the overall reading.

As long as you always use the SAME measuring device. and I prefer the Bikes speedo as it runs from the wheel which is in direct contact with the ground 99.9% of the time ( KTM owners can disregard this statement as the front wheel is usually in the air 15% of the time.)) and therefore is "accurate" to a given degree. the GPS on the other hand is accurate to within 10M.

My GPS reads about 2-3 mph under my speedo which is normal as all bike speeds over read..

so you mean to say I wasn't doing 165Mph when I nipped off for a test ride on the Hayabusa went it first came out?

Now I've got to go and do it all again!

This is slightly rough, but I reckon to get at least 400km from my 23 litre acerbis tank. This is a mixture of riding, but mostly tarmac. I never ride with fuel economy in mind so tend to thrash along fairly quick.

This works out at a little more than 17.5km per litre.

Ted, my bike is also a 2003 model, so it seems the model plus our riding style might be the answer!
