The 2015 Yamaha PW50 is a legendary entry-level dirt bikeultra light, simple, and user-friendly for young riders. Notably, the PW50 is air-cooled, making it one of the few modern minibikes that does not use a liquid cooling system. This means that there is no coolant to change on your PW50. Instead, the engine relies on air flow to maintain optimal operating temperature.

However, with its oil-injection two-stroke engine, routine maintenance is still critical to keep your little ripper running strong. Instead of coolant service, focus on these routine checks:

  • Keep the oil injection system filled with quality two-stroke oil and inspect the oil pump operation at recommended intervals.
  • Clean and oil the air filter regularly to prevent dust and debris from entering the engine, especially in off-road conditions.
  • Inspect the spark plug for fouling and replace it as necessarythis is a key component for two-stroke reliability and performance.
  • Check the fuel system for any blockages or leaks and drain out old fuel, especially after periods of storage.
  • Monitor the drive shaft and shaft lubricationthe PW50 uses a shaft final drive, which requires periodic oil changes.

Key PW50 tip: While the absence of a liquid cooling system simplifies maintenance, never cover the engine shrouds or restrict airflow around the cylinder while riding. Good airflow is vital for engine cooling on the PW50.
