Fuel consumption on my 1150 is rising!! Help

[Rasher]

Hi Guys

The fuel consumption on my 1150GS is rising. I've got around 7500 miles on her having done oil/filter/plugs changes myself but she's never had a proper dealer type service.

Any ideas on what to look for or do?

Thanks

Have you a Y piece and can fitted, my 1150ADV consumption increased dramatically, after it was fitted. Although a lot of that was because I just used to give it handfuls to hear the noise....

Have you fitted panniers?

Fuel consumption will always rise. It's never going to make fuel, is it?

Best get your CO levels checked , theres an adjuster under the seat on the RH side (brass screw) dont be tempted to turn it unless oyuve got a CO meter to check it. Melted piston can get expensive.

only on an 1100, 1150 mixture is controlled by the ECU.

Yes, pray for summer to come early
It's normal that when it's cold, your engine wants more fuel.

The cold air is more dense and contains more oxygen. The sensors in the fuel system "feel" that and to give you a good mixture, they send more fuel into the injectors. Hence you get more power, and you use more fuel.

I have noticed that my bike uses about 10% more in cold weather. Don't worry about it, enjoy the extra power

And welcome to the madhouse

Cheers,
Michel

Have you set the valves and balanced the injectors? May not reduce your fuel consumption but the bike will run smoother and sweeter.

Worth checking your tyre pressures. Can have quite a big effect on consumption.

Have you been consuming more Big Macs/beer?

 

[Rasher]

Thanks for that Guys (well most of it anyway!)

I'll check the areas suggested and keep track of whether the situation improves or not.......as for the Big Macs - well "Rasher" is a bit of a contradiction these days!

If it's a significant rise, it could be the oil-temperature sensor or the air-temperature sensor. The Motronic gets input from both of these to determine whether to enrichen the mixture.

Not convinced by this at all. Colder air should give a more dense charge into the cylinder, which indeed gives more power, and improved efficiency. Assuming your not riding with the throttle on the stop the whole time, I would expect less fuel to be used.
Cold starts and wet roads will both increase fuel consumption.
