This British and motorcycle shop term refers to an engine running at its base idle speed without stalling. It describes the rhythmic, ticking sound a well-tuned engine makes when sitting in neutral. Mechanics adjust the fuel mixture and idle screws to achieve a smooth, consistent rhythm that keeps the oil pressure up without racing the motor.
