Hi , I have 07 superglide that starts fine and rides fine until it warms up,I have done the speedometer tests for codes thru every module and it says (none). When I take off and ride about a quarter mile it will begin to bog down and the longer I ride it the worse it gets until I have to limp it home.Like I said it only seems to do it the warmer it gets. The check engine light comes on when this happens also.I have heard o2 sensor ? Any clues out there? I don't have any breakout boxes to perform various checks , but I have plenty of tools and a vast knowledge of electricity ac and dc.
