Hi is there some one with the same problem and how did you fix it.
My sled is using about 30 Liter of fuel on 150 KM.
It also back fires and hesitates when it has been running for +/- 20 Min .
The dealer has not found the problem and did a flash on the computer ( new 2011 Program ) but that did not solve the problem.:mad2:

Hi Remlar, i also have a IQ cruiser. My friend also has one and he has found a small fuel leak. We haven't found the exact location, but it leaks on the right side onto you right leg. Maybe yours is leaking fuel somewhere and i have no idea why it backfires. Maybe spark plugs?
