Ok i am new to this forum and also new to my bike. I just purchased a fuel injected 2002 Softail Standard for a steal of a deal due to the guy having a friend die. It only had 4700 miles on it when i got it. Well it rides great accelerates fine but when i let off the throttle it pops like it is backfiring. I apologize if this information is already in a different post but i read so much conflicting stuff i wanted to throw out my specs and ask if someone has encountered this problem. What i know about the bike that i bought 2002 Harley Softail standard 5500 miles on it currently (4770 at purchase 1 month ago) Has From what i can tell Python Staggered duals with no Baffles It has a Power Commander III USB module I believe standard air filter As i said i have popping sound when i let off throttle and i am not what it could be caused by whether it be, i have heard many different things and i would like to know where to start. I have heard not tuned correctly, air leak at gasket, python pipes just do that, no baffles, and others. I planned on getting baffles just so i don't make my neighbors mad at 4am but i would really like some help as i know nothing about fuel injection and this bike is new to me.
