interesting read on decel popping Here's some light on the issue: Burn Baby Burn The last thing I want to address today is the subject of deceleration backfire, or “popping”. This topic generates a lot of concern from inexperienced riders, or even from experienced guys who just hate the noise, so lets take a look at what causes it. But first things first, lets define the issue: Deceleration Backfire is caused by fuel burning in the exhaust manifold or header. No ifs ands or buts, that’s what causes it. But the bigger question is how does gas get there in the first place, and that’s a bit more complicated.

- Understanding the fundamentals of charging your motorcycle battery will give you a long and healthy battery life. One of the most common causes of premature battery death is leaving your motorcycle battery in a discharged state, or not charging the battery after use.o successfully float charge a motorcycle battery, you will first need to buy a battery charger that has an automatic float mode such as the Noco genius series chargers or the Battery Tender chargers.

How to Fix a Misfire When a head gasket wears (blows) it can allow coolant or exhaust gasses to enter the combustion chamber causing a cylinder misfire. Helpful Information. An engine tune up is necessary at manufacturers recommended intervals to maintain proper engine run-ability. A misfiring engine will cause, low gas mileage, low power output, increased emissions and possible internal engine damage if left untreated. Typically an engine misfire under load, will be a problem with the ignition system, while low engine speed problems will be a vacuum, fuel management or compression issue.

- This back-seats the valve. Oxygen cylinders must have the valve opened up all the way because of the high pressure in the cylinder. There is a back-seating valve on the oxygen cylinder. This prevents the high-pressure gas from leaking out through the threaded stem.

5 Reasons that Cause Your Car Backfire The valve is the passageway for air to enter the system when the engine is under load. When it’s malfunctioning, it releases air into the combustion chamber even at the time of de-acceleration. It creates the ignition of unburnt fuel and causes a car backfire. ←

Exhaust Popping on Deceleration Exhaust Popping on Deceleration. Deceleration backfire is caused by fuel burning in the exhaust manifold or header. Something you should understand before going any further is that a motor in perfect tune will exhibit deceleration backfiring. Just because your exhaust is popping, doesn’t mean there’s anything wrong.

Tech Tip - Backfiring or Popping on Deceleration Don't change the plugs like some people suggest, it’s a waste of time and money. Messing with the ignition timing really won't help either, because it is still a lean fuel/air mix on deceleration that is the cause. ( I said cause and not problem, because the popping is not at all damaging to the bike).

- Damage of this type may not cause overheating, coolant in the oil or any other outward sign. Many people overlook this as the cause of engine misfires, because the blown head gasket does not also give the other more common symptoms.When the head gasket fails between a cylinder and the coolant port, coolant may leak into the cylinder.ngine misfire caused by a head gasket. A head gasket that fails between cylinders will generally cause a misfire and perhaps few other symptoms. With a failure between cylinders, compression from one cylinder leaks into another. Lowered compression results in a rough idling engine.

Backflow Prevention Backflow, or the reverse flow of contaminated water into a potable water distribution system, is caused by backsiphonage or backpressure. 1  Backsiphonage occurs when low pressure, or vacuum pressure, on the supply side of the connection causes water to be siphoned from the user sideback into the supply.

Why does my engine spit or backfire? Backfiring through the carb (spitting or coughing) usually occurs in the morning when a carb's air/fuel mixture is a bit too lean. This usually goes away once the engine warms-up. It is also commonly caused by the accelerator pump inthe carb not squirting enough fuel before the main jets start working.ackfiring through the carb (spitting or coughing) usually occurs in the morning when a carb's air/fuel mixture is a bit too lean.

The Most Common Motorcycle Accidents (888) 373-5595. The Most Common Motorcycle Accidents. By far, the most common reason for motorcycle accidents is that someone makes a left turn in front of the motorcyclist, or runs directly into the motorcyclist. Most of the cases I handle involve unsafe left turns. These dangerous accidents result in the rider flying forward, often over the vehicle.

How to Quiet Your Motorcycleâs Exhaust The motorcycle’s sound is controlled by the muffler and the exhaust system. The muffler is the main component that reduces sound. The challenge in dampening sound is that mufflers can cause backpressure, which results in a power loss. The solution is to take advantage of aftermarket, high-performance mufflers.

Why does my engine spit or backfire? First off, you need to determine whether it is backfiring out the exhaust or back up through the carb. We usually refer to an exhaust backfire as a backfire, and backfiring through the carb as spitting or coughing.Backfiring is usually caused by a spark plug sparking when it isn't its turn and the exhaust valve is open.ackfiring through the carb (spitting or coughing) usually occurs in the morning when a carb's air/fuel mixture is a bit too lean.

How to Fix Engine Backfires When your engine back-fires it can do so in one of two ways. First and the most common way is when the engine is running a small explosion of un-burnt fuel is ignited inside of the intake manifold creating a loud bang which is the backfire sound you hear.

- Because the ECU is there as a failsafe against backfiring, the chassis of the car isn't designed to normally withstand it. A sturdier exhaust port (such as the Tomei Type 80) will minimize damage to the car's body.

Bubble …bubbles are due to a tire defect, and when we explain the causes, they're quick to state that they don't remember running over a pothole - which is understandable. There are, however, telltale signs inside the tire that point to impact injury as being the cause for the sidewall bubble.

What is cupping of a motorcycle tire? When you slide your hand across the tire, you get the impression of the tread feeling like the teeth on a saw. This type of wear is more pronounced on some tires than others and is caused by the fact that in a motorcycle tire, the tread is rounded instead of flat like a car tire.t sounds to me that the tire is under-inflated which causes more wear on the outsides of the tread, than on the center. Over inflating causes the opposite and wears more on the center of the tread. I hope that ois what you were asking about, and with Motorcycle tires, when in doubt through it out!!!

Tech Tip - Backfiring or Popping on Deceleration 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. It is a popping resonating sound generated by a lean condition on deceleration. When you suddenly close the throttle, the incoming air is choked off and the closed throttle also causes the bike to return to idle on the very lean idle circuit.

This usually goes away once the engine warms-up. It is also commonly caused by the accelerator pump inthe carb not squirting enough fuel before the main jets start working. If you spit the instant you blip the throttle it is probably the accelerator pump in the carb not working, plugged up or out of adjustment.

Quadrajet carb flooding? Report Abuse. You have a heavy float or some dirt holding the needle valve open at the fuel inlet. The float is a foam type of material and when they fail they soak up gas like a sponge and won't allow the needle valve to shut off the fuel to the float bowl. This causes massive flooding.You can buy a float separately if you want to try replacing it your self. The top of the carb will have to come off.he float is a foam type of material and when they fail they soak up gas like a sponge and won't allow the needle valve to shut off the fuel to the float bowl.
