What is a dirt bike spark arrestor?

A spark arrestor is a metal componrent or a mechanical device that traps (arrests) carbon emissions from the engine. When internal combustion takes place it emits hot particles which is destroyed by a spark arrestor.

There are different types of spark arrestors. Understandably, they are said to be any device that prevents the emission of any flammable substances from any sources like dirt bikes, stoves, fire engines.

Due to pollution, large amounts of small particulate matter accumulate within the bikes’ engines, so because of these, whenever you travel sometimes, you may have seen the sparks of fire from the bike.

It’s because of the lack of spark arrestor in the bike. This spark arrestor arrests sparks from the bike.

If you are looking for more knowledge about dirt bike spark arrestors, you should read this article.

Or even if you don’t know how important it is, today’s post is a complete guide about all your frequently asked questions. You will see from its definition to top brands spark arrestors and how to maintain them.    

So today, in this article, I will discuss the spark arrestor, its function, how to clean it, how to check for it, types, and other questions you will be having in your mind.

There are specific countries like the USA where you should not ride your bike without a spark arrestor.

It has become so crucial that there is strict legislation if you drive without a Spark arrestor, and you might also face many problems.

There are also certain countries where riding bikes without Spark arrestor only in specific areas are allowed, and India is one of those countries.

Come on, let’s go into the details.

Work of a spark arrestor:

As said above, spark arrestors work to remove carbon particles and particulate matter from the engines. There are internal and external spark arrestors.

They should be fixed and travel around the forest areas or hilly areas because if sparks are emitted from a bike, there is a hundred percent chance of a disaster.

Many men made disasters that harm the environment, and among them, this is also counted. 

So to prevent this and save the environment from forest or wood fires, most countries laid standards of quality control of spark arrestors, and its presence is mandatory to ride in those containment areas.

So mostly, dirt bikes have the greatest hits of creating such types of sparks from the exhaust system due to less function or lousy condition.

It traps carbon particles of more than 0.023 inches. A wire mesh in the spark arrestor absorbs all the sparks and does not let them out of the exhaust pipe.

How do you know if your dirt bike has a spark arrestor:

Suppose you have no idea about spark arrestors and when you want to travel around forest areas and sometimes when your friends talk about these bike things you need to know about them to have a rapport with them.

So you have to check for spark arrestors in these conditions, and now I will tell you about the method.

You can easily see the printed letters on the back of the exhaust pipe as few dirt bikes are pre-installed with spark arrestors. 

If you didn’t find any printed letters on the back of the exhaust pipe, then put your finger inside the exhaust pipe and feel the steel mesh or disc.

If you can feel the mesh, it indicates that your dirt bike is equipped with a spark arrestor.

Sometimes there may be a tube type of spark arrestor, which you may be able to find if you use a screwdriver.

Sometimes instead of spark arrestors, mufflers are present at the end of the exhaust pipe, which can be easily found in the same way. 

Can I ride my dirt bike without a spark arrestor:

As all of you know, the condition of a dirt bike may create a lot of trouble if you travel by the same motorbike.

Not all dirt bikes are fitted with spark arrestors. As most dirt bikes can create sparks from the bike’s exhaust pipe, you must compulsorily fit a spark arrestor to your exhaust pipe to avoid disasters.

The Spark arrestors decrease the amount of airflow. Thus they impact the performance of your bike.

But It is found out that if you remove the spark arrestor, you cannot find the improvement all of a sudden, And there may be a slight decline in horsepower.

However, installing and removing the spark arrestor may or may not affect your bike as it primarily depends upon your bike’s condition.

For example, the sound of your dirt bike may come down after the installation of the spark arrestor.

Also, the backpressure of your dirt bike will be reduced after removing a spark arrestor; this reduced back pressure can even damage the other parts of your bike, So I suggest you use a spark arrestor and ride a bike with a spark arrestor.

How to maintain spark arrestor:                                       

Although maintenance of a spark arrestor is necessary as it gets clogged easily within a few days, it can also reduce the bike’s performance due to the reduced airflow in the back. 

  • Removal:         

The first thing is to remove the spark arrestor from the exhaust pipe.

  • Clean :              

There are various methods of cleaning the spark arrestor, and I would like to tell you about them. Depending upon the type of spark arrestor cleaning method varies.

There are two types of spark arrestors: disc type and screen type.

For the disc type of a spark arrestor, you have to remove everything and then remove the spark arrestor and then clean each part of the disc filled with clogged particulate matter.

You may need a copper brush or a blow torch, which can burn all the carbon accumulated. The copper brush removes the dirt, or you can use a scrub with fuel to remove it.

  •  Dry:                 

After completing the cleaning process, you have to make sure that you need to dry it for sure. You can use a dry cloth for this purpose or leave the cleansed one for a while.

  • Refit:

You can easily refit the spark arrestor into the exhaust pipe.

Above all, you have to first take care of yourself by wearing safety glasses and careful use of a blow torch as mishandling can cause fire accidents.
