How do you get more hp out of a dirt bike?

To increase horsepower on a dirt bike, consider upgrading the air intake and exhaust systems to improve airflow. Tuning the carburetor or fuel injection can optimize fuel delivery for better combustion. Additionally, installing a high-performance camshaft or modifying the engine internals, such as increasing the compression ratio, can significantly boost power output. Regular maintenance and using high-quality fuels can also enhance performance.
