Hi Folks, You know, usually I don't mind showing my ignorance or inexperience because everyone starts from the same place and ya gotta ask questions to learn. But in this case, I'm a bit embarassed and stumped. I've looked at the diagrams and studied my service manual for my 2000, carbed Fatboy but I can't find the oxygen sensor. I thought it plugged into the exhaust pipes but it ain't there. Neither does it appear on the diagram in the service manual. Now, the pipes have been changed to V & H longshots and I want to change to shortshots because the bike has been lowered and they drag at dips in the road. Help me out here and as usual I'll be most appreciative and a bit more knowledgeable. Thanks. Ishmael PS I also looked at the index of the service manual but it does not list a reference for the O2 sensor.
