Why does your 1996 cbr 900rr backfire and spit fire out the exhaust?

A 1996 CBR 900RR may backfire and spit fire out of the exhaust due to a few common issues. These can include an incorrect air-fuel mixture, which can lead to unburned fuel igniting in the exhaust, or a malfunctioning ignition system that causes misfires. Additionally, a clogged or damaged exhaust can also contribute to backfiring by restricting proper airflow. Regular maintenance, including checking the fuel system and ignition components, can help resolve these issues.
