Why does the exhaust on a Harley backfire?
The exhaust on a Harley is properly tuned from the factory to function coherently with the engine. As soon as the third-party part or an upgrade is performed on the Harley, it starts behaving unpredictably. This can be in the form of a misfire when starting the engine or backfiring.
What does backfiring mean on a Harley Davidson?
Real backfiring means the engine is not properly timed and the fuel/air mix is getting a spark and ignition at the wrong time (when the intake valve is open). Real backfiring is actually the bike “spitting up” in a sense, backwards through the carburetor or intake. So, the popping you are hearing is not back-firing.
What happens when you backfill a Harley Davidson?
Although backfiring isn’t all that bad for a bike, it can cause other problems. When in a confined space, the backfiring can damage hearing. Excessive backfiring can also emit small flames from the exhaust, which can cause a fire. Many of the Harley-Davidson’s that have excessive backfiring have bad mileage because the fuel is being wasted.
Why does my Roadking won’t start and backfires?
I’ve got a 95 roadking, this spring it started running irratically,even just dying a couple times after running good.I replaced fuel valve, wires, plugs.Now it won’t start and back fires as I’m trying to start. Plugs have consistantly had black soot build -up, and I haven’t been able to see any air/vacuum leaks. Any ideas? Thanks in advance.

Why does the exhaust pop on my 07 ultra?
Decel popping is very common. You need to add a Power Commander or Vance and Hines FP3 in order to eliminate this. The m/c needs to be tuned. My 07 Ultra Classic has a Power Commander with true duels and O2 sensor bypass harness and have the same exhaust pop.

Why does my Harley Davidson keep backfiring and sputtering?
About 3-4 minutes of riding it was fine. After work, started bike and it did a half start and died, started up (hesitantly) 2ND time. warmed it up, rode 5 mins backfiring, spitting fire etc. Pulled over, called for a ride. Bought new plugs. When we pulled the plugs the gapping was wrong.
