Recently I serviced two 990 Adventures, an 07 and 08. I had serviced both bikes before, but this time the fuel tanks, especially the left, seem to have grown, being more difficult to reinstall than before. Both bike were from up north were there is ethanol in the fuel. Are the KTM tanks growing like some of the Ducati tanks are due to ethanol? If so, is KTM replacing tanks like Ducati is?
