How To Clean Motorcycle Engine

Cleaning your motorcycle engine is a crucial part of maintaining your bike’s health. A clean engine means better performance, improved fuel efficiency, and a longer lifespan for your motorcycle. However, cleaning your engine can be a daunting task, especially if you’re new to motorcycle maintenance. In this article, we will guide you through the process of cleaning your motorcycle engine to keep it running smoothly for years to come.

Why Clean Your Motorcycle Engine?

Before delving into the process of cleaning your motorcycle engine, it’s essential to understand why it’s so important. Over time, dirt, grime, and debris can accumulate on your engine, causing it to run less efficiently. A dirty engine can also lead to overheating, corrosion, and other issues that can ultimately damage your motorcycle. By cleaning your engine regularly, you can prevent these problems and ensure that your motorcycle performs at its best.

What You’ll Need

To clean your motorcycle engine, you’ll need a few essential tools and supplies, including:

  • Engine degreaser
  • Soft-bristled brush
  • Microfiber towels
  • Water hose or pressure washer
  • Plastic bags or tape

Preparing Your Motorcycle

Before cleaning your motorcycle engine, it’s essential to take the necessary precautions to protect sensitive components from water and degreaser. You can use plastic bags or tape to cover the air filter, exhaust pipes, carburetor, and other areas that could be damaged by water or chemicals.

Step 1: Cool Down Your Engine

First, make sure that your motorcycle engine is cool to the touch before cleaning it. Cleaning a hot engine can cause water and degreaser to evaporate quickly, leaving behind residue that can damage your engine.

Step 2: Remove Loose Debris

Use a soft-bristled brush to remove any loose debris or dirt from your engine. Be gentle to avoid scratching any surfaces.

Step 3: Apply Engine Degreaser

Apply engine degreaser to your engine, following the instructions on the label. Be sure to cover all areas thoroughly, including hard-to-reach places.

Step 4: Let the Degreaser Sit

Allow the degreaser to sit on your engine for the recommended time, usually 5-10 minutes. This will allow it to break down grime and dirt, making it easier to clean off.

Step 5: Rinse with Water

Rinse your engine thoroughly with water, using a hose or pressure washer. Be sure to remove all traces of degreaser and dirt from your engine.

Step 6: Dry Your Engine

Use a microfiber towel to dry your engine thoroughly, being careful not to leave any moisture behind.

Step 7: Remove Plastic Bags or Tape

Remove any plastic bags or tape that you used to protect sensitive areas of your engine.

It’s recommended to clean your motorcycle engine every 3-6 months, depending on how frequently you ride and the conditions in which you ride.

Q: Can I use any degreaser on my motorcycle engine?

No, it’s important to use a degreaser specifically designed for motorcycle engines. Using the wrong type of degreaser can damage your engine’s components.

Q: Can I use a pressure washer to clean my motorcycle engine?

Yes, you can use a pressure washer to clean your motorcycle engine, as long as you’re careful not to damage any sensitive areas.


Cleaning your motorcycle engine is a crucial part of maintaining your bike’s health.
