In a medium bowl, mix curry powder, red pepper flakes, salt, ginger, paprika, cinnamon, and turmeric with water to form a smooth paste. Rub paste into chicken breasts, and place them on a plate. Cover, and allow to marinate for 20 minutes.
Brush grate with oil. Place chicken on the grill, and cook 6 to 8 minutes on each side, until juices run clear when pierced with a fork.
