If you’re wondering how to clean motorcycle engine fins, you’ve come to the right place. Follow these easy steps and you’ll be on your way to shining motorcycle engine fins in no time. The first step is to make sure that your motorcycle is cold. After that, prepare your equipment and tools. You’ll need some Dermal sanding bits, car-friendly shampoo, and Muriatic acid.

Dermal sanding bits

A lot of dirt can collect on the motorcycle engine fins. The dirt is not dissipating heat and can lead to overheating. The best way to clean the motorcycle fins is to get rid of any dirt on them. Even though they are no longer used on expensive bikes, they are popular among cheap models. Here is a step-by-step guide to cleaning the motorcycle fins.

Car-friendly shampoo

To thoroughly clean the engine fins on your motorcycle, use a car-friendly shampoo. The car-friendly shampoo will remove road salt and other fluids from the fins while leaving a crystal-clear finish. It’s important to remember to wear protective gear and a rubber glove while working on your motorcycle. Be sure to scrub the fins with a wire brush and rinse thoroughly with water. Never spray water directly into the engine, as it could damage the fins.

Muriatic acid

The motorbike engine’s fins can become dirty over time, due to exposure to external weather and mechanical fluid. Rust and fading of the metal parts can significantly reduce the performance of the engine, making cleaning them a necessary task. Dirty fins can also lead to overheating and corroded components. A simple solution for cleaning motorcycle engine fins is Muriatic Acid.


If you’re looking to add a shiny new look to your engine, you may want to polish its fins. Motorcycle fins are made of aluminum and require a high-quality polish. You can use an aluminum polish and a cone-shaped sanding wheel. Be sure to use the right amount of polish and squeeze it onto the wheel for the correct finish. When polishing your fins, make sure to warm up your engine before starting, and clean it off with sandpaper after each layer.

Checking before rides

Before heading out for a ride, check your motorcycle’s engine fins. If the coolant lines are clogged, the coolant can’t circulate, and this can result in overheating the engine. To check the fins, use an infrared thermometer to point it at the inlet and outlet of the radiator, and note the differences. If they’re dramatically different, that’s an indication of a serious problem.

Cleaning properly

Like car radiators, motorcycle engine fins can get dirty over time. This accumulation makes them less effective at dissipating heat and makes them more susceptible to dirt and dust particles. Proper cleaning can extend the life of your engine, reduce the chance of overheating, and make your motorcycle look great. Luckily, the process is simple, but it does require some preparation.
