I'd start by removing the cables and string. Twist all to factory specs and reinstall. Check bow specs. If draw weight is low, twist the cables. As cables are twisted to increase draw weight, draw length will also increase. Twist both cables the same number. You may need to twist the string a bit to get draw length back where it was. Lastly check let off. Twisting the top cable (cable attached to the outer perimeter of the top cam) will increase let off. Put in 1/2 twist at a time. Untwist this cable if let off is too high. The number of twisits needed to set let off won't affect draw weight. Be careful not to set let off over 80%. This is for a RH bow.
