The tuner said no matter how he adjusted the fuel lean or rich he couldn't eliminate it . Its on decel at around 4500 rpm.
The bike hasnt been used alot in recent years and the ecu was originally flashed but i dont recall it backfiring this much so thats when i put the pc3 on it to try and rectify it. Any sugestions on what i can do to fix this problem.
