A backfire is a loud micro-explosion which shoots out of the exhaust pipe of your scooter. It can be caused by a variety of things. Most commonly backfiring is a result of an exhaust leak or when your motor scooter is running too rich or too lean, a clear sign of a malfunction in the mechanics of your scooter. If your scooter backfires then you should investigate to see if there are any issues going on mechanically. This guide will tell you what to look out for and more importantly how to prevent backfires from occurring and repair your motor scooter.
Backfires can be spectacular, fire breathing explosions or just minor pops and crackles coming from your exhaust or from your intake. While it sounds rather dramatic for explosions to be occurring within your motor scooter, micro-explosions are supposed to take place in your scooter in the combustion chamber.
When small explosions are occuring in your intake or exhaust then this is a sign that there an interruption present within the emission system of your motor scooter. If you hear audible bangs shooting from your motor scooter then it is a good idea to take a closer look at the first possible moment.
Most commonly backfires occur when the engine of your motor scooter is running rich. This means the mixture of fuel to air within your scooter is balanced too far in favor of fuel. In other words, your engine is receiving more fuel than air , causing an incomplete combustion.
During an incomplete combustion, the heat of your exhaust causes the surplus fuel to ignite and sparks a micro-explosion. As we will discuss, a carburetor cleanup is the best solution to fixing this issue.
Another frequent cause of backfires is when the engine of your motor scooter is running lean. This means the mixture of fuel to air within your scooter is unbalanced with a lack of fuel. In other words, your engine is receiving too much air and not enough fuel. A poorly maintained fuel filter can also cause backfires. If the filter is not changed enough, or if it becomes clogged, backfires can occur. A poorly operating filter can lead to low fuel pressure, which causes backfires.
Likewise, a fuel injection system performing improperly can cause backfires by failing to burn fuel completely. Ray Byrnes began writing for publication in His work has been featured in "Buzz Magazine," online at the and in several literary journals.
He specializes in writing fiction, poetry and journalism. Other causes of backfire are bad or weak fuel pumps, low fuel pressure, or clogged fuel filters. A backfiring or smoking exhaust can indicate either too much fuel or too little spark, both of which can bring about power loss. A backfire occurs when the fuel-air mixture does not fully ignite in the combustion chamber, but instead pops off elsewhere in the system.
The most common cause for this problem is a weak fuel pump which cannot supply the volume of fuel needed for the injectors to produce a proper spray pattern or deliver the amount of fuel needed for engine acceleration.
Some cars have a fuel filter which can also cause a fuel pressure and volume restriction. Popping on deceleration is due to unburnt fuel being ignited in the exhaust. The reason you do not hear this on a bike with a stock exhaust is due to the baffling of the stock exhaust. To REDUCE it may not totally go away popping on deceleration first make sure that you do not have any intake or exhaust leaks.
There are many ways to stop the bike from backfiring and some of them are as listed below. The engine will run clean if the fuel cannot flow properly and the main cause for this is a dirty carburetor. A backfire is caused by a combustion or explosion that occurs when unburnt fuel in the exhaust system is ignited, even if there is no flame in the exhaust pipe itself.
That unburnt fuel can be caused by a variety of mechanical problems, and here are some of the most common reasons for a backfire : Running too rich. Why does my scooter backfire?
