Bikes are supposed to give us the best experience on the roads. Whether you are a dirt bike racer or use your bike to commute to work, exhaust noise can be a nuisance on the road. Sometimes, the noise can divert your attention and cause you to lose performance.
I know that you have wondered whether you can reduce the motorcycle noise or get rid of it altogether. Maybe your question is whether you can retain the bike’s performance when you try to minimise the noise disturbance. The good news is that noise reduction can improve your performance on the road as it gives you a conducive environment to keep racing.
Follow these simple tips to make your motorbike perform better by reducing the noise it produces while on the road.
1. Consider Changing the Muffler
The muffler, or silencer (as the Briton slang puts it), is a part of the exhaust system responsible for keeping the noise at the minimum when you use your motorbike on the road. Most people use the mufflers that come with the motorbikes from the manufacturers.
Although they have no performance issues, the OEM mufflers tend to be the noisiest of all.
For a better experience, you need to replace the muffler on your bike. You do not have to wait for the part to get damaged as other parts before getting the best motorcycle accessories. Mufflers are essential, and you may want to replace them as soon as you buy your bike.
You would want to know what is the best muffler to fit your bike. Experimenting may be a good idea, but it may become time-consuming and costly in the long run. The full case mufflers may be a better choice than the standard mufflers. The two options available on the market are single-chambered and dual-chambered mufflers.
While single-chambered mufflers in the full case class can suffice the needs of most motorbikes, some people prefer dual-chambered ones. The latter splits the exhaust, minimizing the noise more than the single-chambered muffler.
2. Insert a Silencer
A muffler silencer is a device you use to diminish the level of noise from your muffler. The silencer reduces the noise exponentially when you compare it with the standard mufflers. The silencer reduces the size of the exhaust hole and effectively shuts off the noise while allowing combustion and the emission of gases from the bike engine.
Buy a silencer from a dirt bike parts dealer, and insert it into your bike’s exhaust. However, you would first want to verify that it fits your bike. Check to ensure that the silencer’s outer diameter is a little smaller than the inner diameter of your motorcycle’s exhaust pipe.
If you are coming from a ride, you would want to wait for your bike to cool down. Touching the exhaust immediately after a race can be hazardous because it is scalding by then, and it can burn your hands. You may also want to spray some paint on the new silencer to ensure that the colour matches that of your exhaust pipe.
3. Keep Your Exhaust Clean
How do you clean your motorcycle? Have you ever given thought to your bike’s exhaust pipe and muffler? That little thing below the bash plate can make or break your biking experience. Over time, dirt build-up may clog your exhaust.
Clogged exhaust and muffler cause your bike to emit dark smoke while increasing the noise. Such noise can be disturbing, and you would have to clean it up before you restore the bike into sanity.
I guess this option would be ideal to consider before you start changing your dirt bike accessories. You do not need any expertise in cleaning a motorcycle exhaust. When you are well-prepared, you can finish the task in a few minutes and get back on your bike free from smoke and noise.
4. Watch Out for Leaks
Leaks on an exhaust is another culprit you would want to check when you have a noise that seems uncontrollable. Exhaust leaks can be a result of rust or wear and tear. Accidental or deliberate knocking of the system can also cause an issue of making your bike noisy.
Even the tiniest of leaks can cause a massive change in the amount of noise that comes out of your motorbike’s exhaust pipe. You want to patch up the damaged parts to contain the air and ensure that the pipe has only one opening – the one designated at the rear end.
If your bike exhaust is rusty, you’ll need to clean it up before starting the patching process. Depending on the extent of the rust, you may end up with more significant leaks than you anticipated. But it would be beneficial to patch up a more substantial leak than contain the small one that would lead to another in a few days.
5. Check if the Fuel is Burning Completely
Fuel in engines requires oxygen to burn and provide the motorcycle with the energy it requires to propel forward. Because the air contains only 21% oxygen, you need more air supply to facilitate a conducive combustion environment.
When there is insufficient air supply, the gas burns up but produces carbon monoxide and soot (solid carbon) instead of water and carbon dioxide. In this type of combustion, the vehicle has less efficiency because the fuel does not provide the total required energy.
The soot from an inefficient combustion process leads to a noisy motorbike. When the solid carbon forms, you would not miss hearing a cracking or a popping sound – sometimes both. It is easy to finetune your motorcycle’s engine to ensure complete combustion so that your bike can improve efficiency and reduce the production of soot and noise.
There are many reasons why your motorcycle can be too noisy while on the trail. Regardless of the bike you ride, you can substantially reduce the noise from your bike’s exhaust. Reducing the noise could also improve the bike efficiency and achieve the best performance with a quieter machine. Follow the five tips above for the most common issues with bike exhaust noise.
