How to Polish Motorcycle Engine Fins – Keep Your Engine Rust Free

Motorcycle engine fins are usually made out of aluminum. While they are resistant to corrosion, they may get dirty from time to time due to road salt, fluids, road film, and varied weather conditions. This is why, just like you take care of your entire motorcycle, you should ensure that you clean and polish the engine fins regularly. Polishing the fins will bring back the shine and improve the overall aesthetics of your motorcycle. After all, who doesn’t want to ride a glistening vehicle?

In this article, we will walk you through simple steps to help you clean and polish them without wasting time or wondering how to do it right. Let’s begin.

How to clean motorcycle engine fins?

  1. If you took it out for a spin recently, wait for the engine to cool.
  2. Wash the engine fins thoroughly using water. A strong stream of water through a pipe is the best option because it cleans the dirt right out. 
  3. Use car shampoo or specific motorcycle shampoo and mix it with water in a bucket. Using a sponge, use this soapy water for a final cleaning. Make sure you reach the inside of the fins and clean the entire area thoroughly.
  4. Wash the engine with a pipe again so that all the soapy water washes off.
  5. Wait for it to dry.

How to polish motorcycle engine fins?

  1. You need a cone-shaped wheel designed for polishing and some aluminum polish. (Of course!)
  2. Squeeze some of the polish out onto the wheel’s tip after placing it safely on the chuck of the drill.
  3. Now, switch the drill on and insert the wheel on each side of the fins. This will help you reach deep areas that are otherwise hard to clean and polish.
  4. Keep moving the drill back and forth so that you polish the entire surface area. If the polish is getting over, feel free to add some more.
  5. Once you are done polishing, rinse the fins so that all the excess polish drains off. 
  6. Now, take a small cloth or chamois to absorb any residue or water.
  7. Leave the engine to dry.

Important things to keep in mind

  1. Never polish the aluminum fins without cleaning them first.
  2. Using a chamois is a great idea because it removes water instantly. Other pieces of cloth may not be as efficient.
  3. Rinsing is a must after cleaning and after polishing. The rinse should be thorough so that you leave nothing behind.

Polishing the aluminum fins of your motorcycle can actually be a fun project for you over the weekend. Many people also find it therapeutic. Once the polish dries, trust us, you will be extra-enthusiastic to ride it and show off your show-quality upgrade! Have fun!
