2006 Uly. Wanted to check AFV before getting an aftermarket muffler. Reading is 109.9% on rear. I know + - 10% is ok but that is close to the line. I do have a K & N filter and a few extra holes in the airbox so I am thinking this is why the ECU is adding a little extra fuel. Bike runs great. I interpret this as everything (i.e. intake seals) is OK and as expected. Correct?
