You are no doubt shooting the factory strings. They are notorious for creeping, thus throwing the cam out of it's optimum position. This often causes more noise and vibration. You need to check the bow's specs and see if they are what is called for. Possibly need to twist up the rigging to get things more in spec.

And when you get ready to replace those inferior strings get a PM to Gibblet and get some good ones. Usually at no more cost than some generic rigging from most shops.
