You bought a motorcycle because you love riding it. The experience is thrilling in most cases, but there are situations where you might be uncomfortable or even scared.
For example, you might decide to kick on your motorcycle when a loud popping sound appears! At that moment, you startle the people nearby, and you even manage to scare yourself. The sound we are talking about is called backfiring, and we are focusing on it in this article.
What is Backfiring?
A backfire happens because of the malfunction of the emission system. If there is too much fuel or air, that can cause the engine of your dirt bike to backfire. The heat of the exhaust ignites the fuel, which means that incomplete combustion occurs. That leads to the explosion and the uncomfortable sound you hear.
The combustion chamber should be the location of the explosion. But when that doesn’t happen, it causes an engine interruption. Backfiring is the result of that. It might be interesting to note that the exhaust or intake can both be the explosion spot. Although it doesn’t happen often, you might also notice a partial frame coming from the exhaust.
Why Does a Dirtbike Start Backfiring?
If you want to know why your motorcycle backfires, it is because the engine runs either lean or rich. When you hear that the engine of the motorcycle is running lean, that means that there is considerably more air than fuel. The ratio is unbalanced if the bike is running rich, too. However, the difference is that there is much more fuel than air.
The first step in handling the backfiring issue is to test the engine of your motorcycle. If you are willing to do this by yourself, park the bike in your garage. You might need tools like screwdrivers, wrenches, and wire pliers to find the source of the problem.
The first sections to inspect are carburetor and jets. It is easy for dirt and debris to get in these sections and clog them, which might cause backfiring. You want to clean these areas thoroughly, but make sure to get the right cleaning equipment first. You can find specialized cleaner sprays for carburetors, but don’t forget wiping everything with a towel, too.
How Bad is Backfiring for a Dirtbike?
A single backfire shouldn’t have harsh consequences on your motorcycle. Furthermore, the chances are your engine will remain intact. However, if backfiring keeps happening, the chance of the possible damage increases.
Apart from the frequency of backfiring, you should also analyze its severity. Most backfires remind of a mild cough. Not only do they make a similar sound, but they don’t leave consequences on the engine. But always pay attention to the loudness of the combustion.
If you notice that the backfire became louder than before, you should fix the problem immediately. Furthermore, you might want to take your motorcycle to the mechanic right away. Otherwise, you might compromise the lifespan of your vehicle’s engine. You don’t want that to happen, especially if you just purchased a Husqvarna dirt bike or another model, so make sure to take care of the issue quickly.
Ways in Which You Can Prevent Backfiring in Your Dirtbike
You now know the basics of backfiring, but did you know you can prevent it from happening in the first place? Veteran riders know the tricks to minimize the risk of backfiring, and we are sharing them with you below.
Clean the Air Filter
Engine performance and longevity depend on the cleanliness of the air filter. Unfortunately, air filters get clogged frequently. It is vital to get them clean every six months or 3,000 miles (whichever comes first).
If it is necessary, perform the cleaning more frequently. For example, if you like riding your dirt bike on off-road, dirty, or muddy surfaces, air filters might get clogged quickly. Please note that you should also replace your air filters if you notice they are beyond repair. Fortunately, Brisbane Motorcycles and similar vendors should have parts that you need.
