Engine backfire is caused by an imbalance in the air-to-fuel ratio of the vehicle. Backfires occur in one of two places. A backfire in the intake manifold is caused by a ratio that is too lean (not enough fuel). A backfire out of the exhaust system is caused by a ratio that is too rich (too much fue
When a motorcycle engine has an emission system malfunction, such as an exhaust leak or a moment of running rich or running lean, backfire occurs as a result. When an engine is running rich, there is more fuel present than air, according to DoItYourself.com. When it is running lean, there is more ai
Cars backfire for several reasons, including air and fuel mixing due to leaking hoses or other mechanical problems. Faulty spark plugs or wires can cause a car to backfire. It can also occur when shifting to a lower gear in a car with high horsepower.
When the explosive noise of a car backfire occurs, it usually indicates that the air-to-fuel mixture is unbalanced or that a problem exists with the vehicle's timing. A backfire is the result of fuel burning outside to the engine's combustion chamber. Backfires can occur in either the intake system
Backfiring during acceleration occurs when ignition takes place in the intake or exhaust instead of the combustion chamber. The most common causes for backfiring during acceleration include an incorrect fuel-to-air ratio, a faulty ignition and bad wiring.
Car backfires through the carburetor are sometimes caused by a lean air/fuel mixture. Backfires may also be caused by a leaking hose, faulty plugs or the brand of fuel being pumped in.
Some typical Harley-Davidson engine sizes include the 88-cubic-inch Twin Cam 88, the 80-cubic-inch Evolution and the 74-cubic-inch Shovelhead. Some older Harley-Davidson motorcycles are equipped with either the 61- or 74-cubic-inch Panhead or Knucklehead engines.
Superior Car Talk explains that a sputtering and backfiring problem is usually the result of moisture condensation in the fuel system. While the fuel tank may be tightly capped, water can still seep in over time as the result of temperature extremes.
Backfiring can cause serious damage to an engine if the problem is not quickly fixed. The problem can usually be traced to the carburetor or distributor. The carburetor delivers the air/fuel mixture to the engine, and the distributor ignites that mixture within the cylinders. Thankfully, because bot
