If your Harley-Davidson Road King is producing unusual engine noise, losing power, or running rough, it may be time for a valve adjustment service. The valve train plays a crucial role in controlling airflow in and out of the engine — when it’s out of spec, performance and reliability suffer.

Our Valve Adjustment Service is designed to restore proper engine timing, eliminate excessive noise, and improve overall performance — keeping your Road King running smooth, quiet, and strong.
