First, Bigpapascout is correct about timing the bow at full draw, and that the binary cams can indeed be out of time. They are connected together and what the "slaved" means is that when one stops rotating, so will the other, where as a traditional 2 cam bow one will hit the stop and the other will continue to rotate until it hits it's stop, causing eratic nock travel at the critical end of the draw as the string continues to let out of only one cam. The binarys cams can be out of time, but the ill nock travel effects are minimized due to both cams stopping and one not being able to rotate independantly. It is a good idea and the 07's are much better than the previous versions as they load the axles closer to the center and do not exhibit the "lean" that previous ones do.

Now, on the 03 dually, there are 2 things that can cause the double hump you are feeling. One is out of time at full draw, the other is that the early Bowtechs needed to have a slight amount of induced "lean" by manipulating the yokes so that the cable falls into the groove on the cam smoothly -- if not, it can hit the side first then "jump" into the groove causing the double bump. Also, make sure you shoot the cables in. Ensure that the cables are not hitting the side of the track while you draw and adjust yokes 1/2 twist at a time until it fallin smoothly. Get it timed at full draw with YOU drawing the bow. The way you pressure the grip can have an affect on the timing. If the draw is not exactly as you want after this, adjust with twists in the string.

One other thing, when changing modules, ensure they are really seated when you tighten the screws -- there is enought play in the fit to tighten them and make them slightly off. This may have been what happened to you initially.
