Have you checked the brace height? If the brace height is not in tolerance and too low for the bow, then the draw length can be too long. If the brace height needs to be adjusted higher, refer to the Cable and Brace Height Charts and instructions in the Manual at the links below. To increase the brace height, you must remove the bow string from the bow and add twist to the bow string.
