Abstract

A motorcycle engine having a pair of cylinders, a piston disposed in each-cylinder, rotatably mounted flywheels, a crank pin mounted on the flywheels, and a connecting rod assembly for coupling the crank pin to the pistons. The connecting rod assembly includes a master connecting rod having a connecting rod portion connected at one end to one of the pistons and a base portion at its other end. A cap is removably mounted on the base portion and defines with the base portion a coupling for receiving the crank pin. A split bushing is disposed between the coupling and the crank pin. The connecting rod assembly also includes a slave connecting rod connected at one end to the other piston. An aperture is formed in the base portion, a second bushing is disposed in the aperture and a pin is disposed in the second bushing. The other end of the slave connecting rod is pivotally mounted on the pin. Oil ports are formed in the split bushing, the base portion and the second bushing for defining an oil passage between the pin and the crank pin.
