Does anyone have any idea why my 2010 has developed a serious drinking problem? I used to get about 300km out of a tank, today I ran out at 220, for the second time. And no, the gauge doesn’t work. Thanks all.
Now wouldn’t that be ironic, the government introduce a 5% increase in biofuel to save the planet without realising it results in a drop of 25% in fuel economy! Presuming you’ve no faults appeared on the dash? The map sensor failed on the horizontal cylinder on mine, aside from the error on the dashboard the signs were lumpy running on idle and an unburnt fuel smell from the exhaust so probably running rich which would affect the mpg.
Fuel economy with E10 is estimated as being 7% lower (worse) than with Premium. So with the performance being dulled down too, its worth thinking about paying the extra for Premium petrol.
Thanks all, but no E10, and no faults on the dash. Tyre pressure good, colder weather should improve efficiency, I just can’t figure it out.
I’m not sure but it may be the Air Temp Sensor(may already have been mentioned, MAF sensor?) but as I recall on my 2011 model, this is the sensor, which controls the motor fuel on start up. Effectively, an auto choke, running the engine quite rich. If this is faulty it will run the engine rich constantly. Additionally, make sure it hasn’t got disconnected nor the tube connected hasn’t been crushed, blocked etc. Is your exhaust tip quite sooty? If so, this could be your issue. As I recall it’s situated inside the nose of the bike.
My memory is telling me that there was a post, probably about 2 years ago, about the same issue. Just not been able to find it or remember what resolved the problem. It certainly sounds like a ‘failure’ of something and I’m not sure that a MAP sensor failure actually throws a fault on the first generation 1200, when one of mine failed, I don’t remember a fault light.

Andy: I think the MAP sensors do throw a light up. I had one fail. Pro-Twins connected their lap top and confirmed which one (One per cylinder, as I recall)
That’s what I had on my ‘13 model, a new sensor sorted the issue, I didn’t really ride it enough to notice any change in mpg but it was running rich but did throw up a fault but then the twin spark is a later Gen? About £80 for a new sensor if I recall. https://www.ducatiforum.co.uk/threads/typical.77943/
Could this be one of those 'Disconnect battery. Make and drink tea. Have a fag. Re-connect battery' issues? (ECU reset)
