Why does my bike keep backfiring?
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’s the problem with my 1988 Springer Softail?
My 1988 Springer Softail has had a problem over the last 5 years or so, always the same thing. It runs like its only hitting on one Evo cylinder sometimes, but all of a sudden it will start running fine. I have had it in the shop a couple times only to have them work on carb but problem still happens.
Can a worn out timing belt cause a backfire?
A worn out timing belt can upset the combustion process and lead to backfires. Gasoline engines need to fire spark plugs on time to properly ignite the air-fuel mixture inside a cylinder. On time means that sometimes the spark needs to be fired ahead in advance or retarded depending on engine speed and load conditions.
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.
Why does my Softail Deluxe bike run weird?
Mine would do the exact same thing, its a 2007 softail deluxe. It turned out the battery to be the problem. The reason its intermittent is the bike will start running weird in other words it would take a charge but if for some reason that charge did not hold for long the bike will start running weird again.

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.
What does it mean when a motorcycle backfires?
Backfiring on a motorcycle is the popping sound of unburnt fuel igniting in the exhaust. This typically happens during deceleration. While the popping itself may not be harmful, it does indicate that your bike may not be tuned properly, which CAN lead to harmful problems.
Why does my Harley backfire when I Turn Off the ignition?
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. The ignition is then turned off and then on again with the throttle turned all the way up.
