990 Super Duke fuel consumption gone mad? :O

Hi guys,

I've got a 2011 model 990 Super duke with full Akra pipes, with around 7000km on the clock. I bought it second hand in May with only 3900kms on it and it's been great fun. I didn't use it for about 3 months as I was traveling for the summer.

Now after coming back, I've noticed the fuel consumption is a little crazy.. I'm pretty sure I used to get around 180km at least on a full tank, before the fuel light went on (and stayed on). Last week, the fuel light went on at 140km and today, it came on/off at around 100km and stayed on after 120km. This cant be normal?

Currently this would mean that the fuel consumption is around 13-15l/100km or 19-22mpg

This can't be normal? That's more than on my old BMW 330ci..

Should be noted that before I used to live in Milton Keynes, where I traveled distances of around 6 miles a few times a day. It was dual carriageways with lots of roundabouts, so mostly full acceleration / fun ride mode on. Now I'm living in Canterbury, where I'm traveling a very short distance (1 mile) many times a day, and there's a lot of traffic.. But mostly I ride economically, apart from maybe fun riding 30% of the time.

Sounds about right, I do a 5km commute to work each day through urban roads. Fuel light goes on at around 130 and my fueling is all sorted with a custom map. Was worse with akro map.

If I where to go on a big ride up the mountains I get to at least 200km before the light comes on.

Just guessing but maybe the bike drinks a lot of fuel when its warming up which is why short trips guzzle the fuel. Also the SD could be quite a thirsty bike when just idling at lights.

I warm my bike up for 30 seconds However the climate here is warm if that makes any difference

Its a good idea to change oil more often if your doing short trips also.

They are not the most economical bike around but they are a heap of fun.


I don't get it either how these small light vehicles drink the same petrol as a family car lol

I don't commute on my bike but I usually get 220 to 230 before the light comes on?
When I fill the tank I squeeze as much as I can in there.
PS how you going Natedog?

I think you might need to check your air filter there could be rodents living in there I'm serious.viewtopic.php?f=5&t=11617&p=133243&hilit=mice+airbox
Also get a tuneecu cable and check what map your running.

I'm at Murwillumbah

Nice place to live! The roads down there are great too, my SD felt right at home on those bumpy corners haha loved it!

Yep great roads not I met you dudes a few years back at the servo I have a black SD.

Update:

After riding very economically since the last refill, the fuel light is on again after only 120km. :/

I checked the air filter, and it seemed normal to me, see photo:

I don't know what else to do anymore.. should I just bring it to the nearest KTM dealer?

Have a look here its a car site but it might give you a heads up on what to look for http://www.aa1car.com/library/poor_fuel_economy.htm

Is it actually high fuel consumption or low fuel light coming on early?
