Have you ever encountered a burning smell after a motorcycle ride? Even though the motorcycle still runs normally, the smell should not be ignored. In some cases, it may be caused by components that are overheating, but there are also situations where a burning smell is an early sign of more serious damage.

The earlier the cause is identified, the easier and cheaper it will be to repair. If left alone, a small problem can turn into damage that can affect the performance and safety of the motorcycle. Here are some of the things that can cause a motorcycle to create a burning smell.

1. Engine Oil Hasn’t Been Changed in a While

Engine oil acts as a lubrication for the internal components of the engine and helps control the temperature of the motorcycle during operation. When engine oil has been used for too long, its ability to protect engine components will decrease.

High friction causes the engine temperature to rise and in some cases can create a burning smell. If you also feel like the engine feels rough or the motorcycle is less responsive, it may be time to check the condition of the engine oil.

2. Oil or Fluid Drips Onto Hot Engine Parts

Sometimes the burning smell doesn’t come from the engine itself, but from oil or fluid that is spilled on to hot components. For example, engine oil that leaks or spills while being filling can come into contact with the hot engine block or exhaust and create a burning smell when the motorcycle is being used. If you can smell it, try checking for oil stains on the engine or where you parked the motorcycle.

3. Overheating Braking System

A brake system that works too hard can also produce a burning smell. This situation often happens when going down a hill while continuously pressing the brakes or when the brake pads are too worn out.

In certain circumstances, a stuck brake caliper can also cause the brake pads to constantly rub against the brake disc, generating excessive heat. If the burning smell comes with an abnormal brake feel, it is better to stop the motorcycle in a safe place and check the condition.

4. Clutch is worn out

For motorcycles that use a manual clutch, a worn out or overused clutch can produce a burning smell. This usually happens when the clutch is at it’s friction point a lot when moving slowly, climbing hills or while riding in traffic jams. Apart from the burning smell, you may feel the motorcycle losing power or the engine roaring but the speed does not increase as usual.

5. Faulty Wiring or Electrical System

A burning smell can also come from the electrical system. Damaged wires, melted insulation due to heat or a short circuit can produce a burning plastic type of smell. This should not be ignored as it can cause damage to the electrical system or worse, a risk of fire.

If you smell something like burning wires or see smoke coming from a certain part, stop the motorcycle immediately and do not continue riding until you have checked the cause.

6. Garbage or Plastic Stuck to the Exhaust

Sometimes the cause is not as serious as you think. Plastic bags, dry leaves or other materials may stick to the exhaust while the motorcycle is moving. When the exhaust gets hot, the material will start to burn and produce a strong burning smell.

Although this problem is usually easy to solve, make sure the exhaust is completely cooled down before attempting to remove the stuck object.

When Do You Need to Take Your Motorcycle to a Mechanic?

If the burning smell only happens once and is caused by plastic stuck to the exhaust, the problem may not be that serious, but if the burning smell keeps recurring, accompanied by smoke, oil leaks, warning lights, unusual noises or changes in the motorcycle’s performance, don’t ignore it.

An initial inspection by a mechanic can help to identify the actual cause before the damage becomes far more serious and requires high repair costs.

Conclusion

A burning smell from a motorcycle is not something to ignore. It can be caused by old engine oil, an oil leak, an overheating brake system, a worn clutch, an electrical problem, or an object stuck to the exhaust.
