I have an 02 Electra Glide ,V & H true duels ,203 cams , Stock air box / K & N filter& S E slip-on's . I don't have any popping but to look at the pipes it seems like it is lean. When you wipe your finger in the end of the mufflers it is clean. I have the bike stored right now due to the weather and don't know what my settings are. Also seems like I had alot more heat comming off the rear cylinder than it usually did. Thanks Clap
