Regular maintenance and oil changes are essential for a well-performing engine. Make sure to follow the manufacturer's recommended schedule and use high-quality oil.

Consider upgrading your air filter to a high-performance one. This will improve air flow to the engine and can lead to better engine performance.

Check your spark plugs and replace them if needed. Old or worn out spark plugs can negatively impact engine performance.
