There are a few things you can do to clean motorcycle engine fins. The first is to use a mild soap and water solution to clean the fins. This will remove any built-up dirt, oil, and grease that may have built up on the fins over time. The second step is to use a hairdryer to dry the fins. This will remove any excess moisture that may have been present on the fins over time. The final step is to use a vacuum cleaner and bucket to clean the entire engine bay. This will remove all of the dirt, oil, and grease that may have been present on the engine bay over time.
