What causes a motorcycle engine to backfire?
Motorcycle backfire is something that happens when a motorcycle engine gets too much fuel or air. Bikes comes setup so that the carburetor (or fuel injection system on modern bikes) provides the correct ratio of fuel and air, to allow the bike to run at its best.
What causes a Harley Davidson engine to backfire?
The stock muffler and exhaust on a Harley Davidson are tuned in such a way as to decrease the sound and effects of a backfire. An aftermarket exhaust can let more air into the bike’s intake, leading to more audible backfiring. Another common practice to cause a backfire is riding the bike in gear to revs upwards of 3,500RPM.
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).

Why does my Harley Davidson Evo keep missing?
It starts fine (kick only) and idles well, usually it even runs fine if you are using very little throttle, although I seem to feel a little surging even then. When you go to give it some throttle though, it starts spitting back through the carb and missing.
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.
