The invention discloses a running method for a control device for synchronously controlling a lubricating hole through a piston. When the piston ascends, a valve ball is made to jack an oil outlet hole of an oil pool through a spring, the oil outlet hole is sealed, and lubricating oil sprayed out of a connecting rod is guided into the oil pool to be stored through an oil guiding groove. When the piston descends, a skirt part of the piston jacks the valve ball away, the lubricating oil in the oil pool arrives at the air inlet side face of the piston from the oil outlet hole, the piston drives the lubricating oil to enable the air inlet side of a cylinder and the air inlet side of the piston to be covered with an oil film layer, and the process is circularly conducted. The running method has the beneficial effects that a motorcycle cylinder lubricating system is improved, the resistance caused to running of an engine due to excessive lubricating oil is effectively reduced, and the functions of saving fuel oil and prolonging the service life of the cylinder are achieved.
