In large bowl, whisk eggs, yolk, pepper and 2 ¼ ounces of cheese. Set aside.
Bring lightly salted pot of water to boil over high heat. Add spaghetti, and cook according to package directions.
Meanwhile, warm large, heavy-bottomed skillet (not nonstick) over medium heat. Add pancetta, and cook until golden-brown and almost crispy, 6–8 minutes. Lower heat, and keep warm.
Reserve ½ cup pasta water, and drain pasta. Add spaghetti to skillet with pancetta. Using tongs or wooden spoons, toss pasta with pancetta. Turn off heat.
Whisk together reserved pasta water and egg mixture, then pour into pan. Working quickly, toss pasta to coat, until sauce is thick and glossy. Add salt, to taste.
Sprinkle remaining cheese on top. Serve immediately. Serves 4.
