First the S-beam is longer on the left side. The reason for this is to provide more room for the exhaust INSIDE the motor mount tubes. On the right side, the S-beam is shorter to provide more room for a cool side radiator OUTSIDE of the motor mount tubes. Also, at work is the right thrust angle of 1.25 degrees. Despite the optical illusion, the engine is on the design thrust line.
