    Default Can someone explain how moving draw stop messes up cam synchronization

    been messing with my onza trying to find the perfect draw length and let of combo...after moving the module to a half inch longer and then moving the draw stop to get it back to where it was with less let off, the am sync was off....so I adjusted the cables and got it sync...was at the range today and moved the stop a little and the arrows were hitting way off....pull it down on a bow hanger to only find the sync was out....i thought since the cams were slaved to each other that if the bottom cam was changed due to the draw stop, the top one would also adjust itself and maintain the sync...what gives???

    You are correct, the cams are slaved and the draw stop doesn't affect the sync. I'm not sure how you're getting problems out of moving the stop...

    great...something must be screwed upchecked one of the cables and the string for length and they were right on the money....attempting to fix it bu placing it on the draw board...drawing it to 28.5"....placed the draw stop at the limb and marked it...now i'm subtracting twists from each cable to try top retard each cam, but after 7 untwists , it doesnt seem to be getting any closer to the cam stops...any ideas?

    I'm not sure if this will explain it, but I think I know what is going on.

    The draw stop is only on the bottom cam.

    When you draw back your bow, the bottom cam stops but the top cam will keep advancing to the bottom of the valley. Lengthen the draw lenght about .5".

    Watch the cams closely and draw very slowly, mark your cams in 1/4" increments with a pencil and as you draw the bow watch as to where and when they go out of sync. I think you will see they are synced up until the very end.

    I can't see any other way that just moving the draw stop alone could make a difference in cam sync.

    You may need to resync the cams now because of the adjustments you already made to them. Sync up the cams without a draw stop in place at all. You really do not need a draw stop, just find a good solid anchor point first. Then set the draw stop to match your anchor point.

    Mike...the cams are not out of sync really...they just are not coming to the draw stops when use the draw stop to stop the rotation at 28.8 with the module set on 28.5.....almost like the 28.5" module setting is really 29"

    You sure you have them mods on the correct number for the draw you are looking for?
