Service Description

If your machine is performing poorly, starts hard, backfires, or has a noisy valve train, it may be time for a valve adjustment. The valves are timed to the piston movement via the timing chain and other components. If your valves are out of adjustment, the motor’s intake stroke, power stroke, or exhaust stroke may stop working correctly.
