I have an 03 injected Road King that pops thru the intake sometimes at idle but mostly just off idle like when pulling away from a stop. At times it will do it between gear changes only at low rpm. The bike has been sitting for a while and I just bought it but it only has 1600 miles on it. It appears to have a stage 1 download as well as K&N air filter and Screaming Eagle slipons. I put a Fuelpak tuner on it in an attempt to fix the problem. Problem may have lessened but is still there. It is really anoying. The bike runs great other wise. I have also added a fuel cleaner like Seafoam to the fuel trying to clean any residual bad fuel it may have in it. Just as a side note, there is quite a bit of popping from the exhaust on decel as well. Seems more than usual to me. Any ideas would be greatly appreciated. I see quite a few posts on the subject but not many concrete solutions


i am reposting this under engine/fuel/intake/exhaust

 

im no expert but have been down the fuel pak road before,
in my limited experience get a better tuner such as a power commander (i have one on my 03 king) and have a good tuner shop tine the bike
had mine done and have no popping, other than a noisy engine mine runs great

good luck
