I just received a 1969 Bear Kodiak Hunter. I am getting some vibrations in the limbs when I shoot this bow. I have tried a brace height of 8" to 9". There seems to be less vibration at 8.5". I do shoot 3 under. I checked the tiller and it is 5/8" difference from the top limb fadeout to the bottom limb fadeout. I have a 1969 K-Mag with 3/8" tiller with no vibration and a 1969 Grizzly with 1/4" tiller with no vibration. Do you know if 5/8" tiller is standard for this bow or is it out of tiller? If it is out of tiller, what are my options? Thanks!
