The engine is the heart of a motorbike, keeping it running for a long time if maintained properly. A well-maintained motorcycle that has not suffered severe damage in an accident or a crash can last for 12-15 years.

Different types of motorbikes have different average life expectancies. On average, a sports bike has a mileage of around 25,000 miles. Meanwhile, touring motorbikes and cruisers can reach a high mileage between 40,000 to 50,000 miles.

A motorcycle’s average life expectancy and total mileage cannot accurately provide you with insight into the vehicle’s overall condition. The longevity of a motorcycle depends on how well it has been taken care of throughout its use.

It is good to keep your motorcycle’s engine clean since it not only gives the engine a lustrous look but also ensures certain engine components will not go out of order. This article explains how to properly clean a motorcycle engine and the supplies you will need.

2. How to Clean a Motorcycle Engine

2.1 Remove the Dirt Using an Air Compressor or Air Blower

Start by removing the dust particles stuck inside the engine’s cylinders and on the spark plugs by using a heavy-duty air blower. This will help get rid of contaminants that may stop the engine from working properly. Removing dirt using an air blower is a simple process and does not take much time.

2.2 Removing and Covering Sensitive Parts

The next step involves using water to wash the engine, but there are certain engine parts that are vulnerable to water damage and should be removed first. The parts that should be removed include the air filter and the air box. Meanwhile, other parts, including the exhaust, spark plugs, fuse box, and ignition coil should be covered using plastic bags and duct tape to prevent water from spilling on them. Remove any fairings or covers that restrict you from having full access to the engine.

2.3 Remove Grease from the Engine

The next step is to remove grease from your engine. This can be done by applying a motorcycle degreaser to the engine. Degreasers are cleaning products used to remove the grease from metal surfaces and engine parts. Make sure to read the instructions carefully before applying the degreaser and cleaning the engine case. Usually, after applying the de-greaser, you should wait for 15-30 minutes.

2.4 Wash the Grease Away

Wash the grease and degreaser away using water. Make sure to rinse every part thoroughly, especially the cylinder fins as it is difficult to remove dirt from tight spaces. Wash until the degreaser is completely removed from the engine’s surface.

2.5 Scrub

Grab a bucket containing soapy water, a soft scrub brush, and a sponge to clean off the remaining dirt or stains. Stubborn dirt particles and stains cannot be easily removed until they are treated with a sponge or a scrub brush. Make sure you do not apply too much force as it might scratch the metallic surface. Use a soft scrub brush and sponge to wash the surface gently.

2.6 Dry

After you are done washing the engine, it is time to dry it. Use a microfiber cloth to rub down the surface and absorb the moisture, making sure to dry it thoroughly. Use the air blower again to dry any remaining moisture to prevent rusting. Before you move on to the next step, leave the engine on for at least half an hour to help with air drying.

2.7 Use a Rubber Seal Protectant

Use a rubber seat protectant as explained in the instructions written on the packaging. The rubber seal protectant will help keep your engine protected and ensure better performance for a longer period. Make sure to thoroughly apply the rubber seal protectant to parts like plastic shields, hoses, and fittings.

2.8 Time to Use the Polisher

A chrome polisher gives chrome engine parts their lustrous look. Make sure to use the chrome polisher as per the instructions on the bottle. You can apply the chrome polisher using an unused microfiber cloth. Give the chrome parts a gentle buffing for a few minutes until the surface shines.

2.9 Reattach the Parts Removed

Reattach the engine parts you removed before washing. Also, remove the duct tape and plastic bags you used to cover the other parts vulnerable to water damage.

2.10 Start the Motorbike and Take a Small Ride

Starting the motorbike and taking a small ride will help dry up any remaining moisture on the engine.

3. Frequently Asked Questions (FAQS)

3.1 What Are the Motorcycle Engine Fins?

When you ride a motorcycle, the engine produces heat which is released into the atmosphere. The engine fins are on the exterior of the engine’s cylinders. The engine fins help maintain the engine’s temperature. The air enters the engine using these fins. The engine fins’ large surface area can take in more air which helps prevent the engine from overheating.

Unfortunately, there is a high chance of the engine fins becoming clogged. Clogged engine fins can reduce the engine’s performance, so it is best that the motorcycle engine is cleaned regularly.

3.2 Can You Use WD-40 to Clean a Motorcycle?

WD-40 is a multipurpose substance used to clean dirt, stains, and rust. It is also used to clean chrome parts, but can be used on different materials, including plastic, carbon fiber, chrome, and aluminum.

3.3 Where Can I Buy Motorcycle Engine Fins, and How Much Do They Cost?

You can find engine fins online and at your nearest motorcycle shop. Make sure you buy quality products by checking online reviews. Prices can vary depending on the quality and retailer. It can cost you around $50-100. Before purchasing, make sure the engine fins you buy are compatible with your motorcycle’s model.
