Shop parts for a 1995 Yamaha PW50 Dirt Bike.

The Yamaha PW50 is a legendary beginner's dirt bike, recognized for its reliable performance, simple two-stroke engine, and user-friendly maintenance requirements. However, if you are looking to change the coolant on a 1995 PW50, there is an important detail to note: the PW50 is an air-cooled engine, not liquid-cooled. This means the engine relies on airflow and fins on the cylinder and head for cooling rather than a liquid coolant system.

There is no coolant to change on a 1995 Yamaha PW50. Instead, regular maintenance involves:

  • Cleaning the cooling fins on the cylinder and head to ensure proper airflow and prevent overheating.
  • Periodically checking and cleaning the air filter, especially when riding in dusty or wet environments, as an obstructed filter can reduce engine cooling efficiency and performance.
  • Maintaining correct oil levels in the two-stroke oil reservoir. The PW50 uses two-stroke injector oil, critical for both lubrication and engine cooling. Always use the recommended two-stroke oil and inspect for leaks.

PW50 Owner Tip: Unlike liquid-cooled motorcycles, there are no radiators, coolant hoses, or coolant system components to service on the PW50. Focus your cooling system maintenance on keeping the engine and its fins clean and clear of debris. If you notice the engine running excessively hot, check for blockages in the fins, improper oil mixture, or airflow obstructions around the engine.

For continued peak performance, regularly follow the recommended maintenance schedule for air filter, spark plug, and oil changes. If you need parts or are looking to stock up on maintenance supplies, be sure to Shop parts for a 1995 Yamaha PW50 Dirt Bike.
