1998 roadking classic EFI screaming eagle pipes exhaust pop on decell how do you fix?

1. Check the fuel mixture. A lean fuel mixture can cause popping on decel. Try enriching the mixture slightly by turning the fuel screw out 1/4 turn at a time until the popping stops.

2. Check the spark plugs. Worn or fouled spark plugs can cause popping on decel. Clean or replace the spark plugs as needed.

3. Check the exhaust system. Leaks in the exhaust system can cause popping on decel. Inspect the exhaust system for any leaks and repair as needed.

4. Make sure the air filter is clean. A dirty air filter can restrict airflow and cause popping on decel. Clean or replace the air filter as needed.

5. Tune the bike. If the popping on decel persists after trying the above steps, it may be necessary to tune the bike. This may involve adjusting the carburetor, fuel injection system, or ignition timing. It is best to have the bike tuned by a qualified mechanic.
