In a small bowl, combine the oil, soy sauce and ketchup. Add the black pepper, if desired. Mix well. Place the pork ribs in a pan. Pour the marinade over the ribs and allow them to sit for 10 minutes.
Heat the grill to 400 degrees Fahrenheit.
Place the ribs on the hot grill and allow them to cook for 5 minutes. Turn the ribs, being careful not to puncture the ribs, which would let the juice escape.
Grill the ribs for an additional 4-5 minutes, or until the internal temperature of the ribs reaches 145º Fahrenheit.
Allow the pork to rest for 3 minutes, then serve.
