Why does my Harley pop on deceleration?
Decel popping is caused by the detonation of unburned fuel in the exhaust pipe. This happens with high flow exhausts that allow more fresh air to be pulled into the pipe, causing the exhaust temperature to rise and detonate any unburnt fuel.
What causes backfire on startup?
Backfiring problems can also originate in the fuel system. Usually, when an injector clogs or wears out, causing the air-fuel mixture to lean, the combustion process weakens and fails to properly burn the fuel. Too much unburned fuel then enters the exhaust system where the fuel ignites with a loud bang.
