How does a Harley Davidson backfire on deceleration?
When it comes to backfiring on deceleration, the bike typically backfires through the exhaust pipes. In the event of a backfire when accelerating, the Harley backfires through the motorcycle’s combustion chamber. The combustion chamber and the exhaust pipes and wiring are all part of a Harley Davidson exhaust system.
How to fix a Softail engine that won’t fire?
Re: My softail will not fire, it just turns over until I… is plug wire good and connected good. Are you getting voltage to one side of the coil with the switch on the run position. will the coil make a spark when you pull the coil wire out and hold it close to the coil and turn engine over.
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 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.

How does a Softail work on a Harley Davidson?
Late model Softails use a complex network of computers to monitor the engine, transmission, and braking system. These systems must stay properly powered by the battery. The wiring connecting the systems together must remain intact. These problems occur and, although difficult to find at times, a series of test will help you narrow down the cause.
Why does my Softail air cleaner not fire?
My softail will not fire, it just turns over until I run the battery down and it will not turn over any more. I tried spraying starting fluid into the air cleaner with no success.
What causes no start on Harley Davidson Softail?
A parasitic draw occurs when one or more circuit remains powered after the ignition is turned off. A draw on the battery of more than 0.02 amps can deplete the battery overnight enough to create a no start problem. To test for a parasitic draw, place your multimeter to the amps setting in series with the battery.
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.
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.
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 to do if your Evo backfiring is missing?
Checked the compression, checked the pushrods and the valves to see if they were opening. Put in new exhaust seals. Checked the timing, checked the coil. The VOES is working correctly. I’ve got good fuel flow. I even put another CV from my buddy’s bike on and no difference. Anyway, I am stumped and don’t know what to try next.
When did my Wife’s Harley start to misfire?
My wife’s 2005 FLHTCUSE2 began to develop problems a few weeks ago. After a short ride, we stopped for her to get gas. On the way home, her Harley started to misfire and run poorly. I lost sight of her so I pulled over. After about 15 mins she showed up and said her bike would not stay running.
Why does my Sportster backfire all the time?
Hi Anonymous, popping, coughing, spitting, or backfiring through the carburator or induction module is usually caused by air getting sucked in combustion chamber do bad intake seals leaking. Leaking exhaust gaskets can also be suspect.

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 to do when your Harley starts to misfire?
The bike would start at high idle and then slow to a stall. We then did a “wild” code check on the motorcycle and got a code for the Powertrain), P1356-no fire at the rear jug. We fixed the wire at the coil, and tried to start the bike again with the same result.
What causes a Harley Davidson engine to ” fire “?
The engine is still spinning but the incoming fuel rate is very low, until just enough builds up in the combustion chamber to “fire” on the exhaust stroke of the engine. Don’t “change the plugs” like some people suggest, it’s a waste of time and money.
Why does my motorcycle backfire all the time?
If your motorcycle only backfires at very specific times, such as when it’s really cold, really hot, when it rains, when you turn left, etc. then you could possibly have the issue of intermittent spark.
When does a Harley Davidson engine misfire at low speeds?
However, when cruising along about 25-30 mph (in either 2nd or 3rd gear) it is always misfiring and sputtering pretty bad now (had a little hint originally and definitely getting worse now). After coming to a stop, the idle is a bit rough and sometimes the engine acts like it wants to cut out for a few seconds after which it seems to idle OK.
What causes a car exhaust pipe to backfire?
Backfiring happens all the time, in cars and bikes, you just don’t hear it because the muffler/exhaust. Since you’ve modified it, now you do. What it is, is incomplete combustion, fuel is left over, and shot into the exhaust pipes. The heat from the pipes then ignites the vapor and boom, backfire.

Why does my motorcycle engine keep backfiring?
When you are getting too much air and not enough fuel in your cylinder this is called running lean. A lean condition in your engine is terrible for the engine internals. Too little fuel in the cylinder and an excess amount of air can be the culprit to your backfiring problem.
