Hey guys, I'm sorry to post about a subject that I know has been brought up before, but I'm confused. I'm new to bow hunting this year. I bought myself a Hoyt UltraSport (29" draw length, set at around 63 lbs). I'm shooting Carbon Express 300's. Here's my problem.
When I first bought the bow, it was set at 60lbs or so. I shot it several times and it was really quiet. I called the shop to make sure that I could adjust the weight at home by myself, and they told me that with this particular model, all I have to do is turn the bolts. So I did one full turn on each limb to get it to 63-64 lbs. I shot it twice before the bow started making noise when shot.
The last two times I've been out shooting with it, it makes this TUNG noise that sounds like something is vibrating. It also seems like I'm feeling increased hand shock. Even with a stabilizer on it still makes the noise. Any ideas? I'm going to try to get it in to the bow shop this weekend, but it's bugging the heck out of me in the mean time.
For starters you need to get a set of allen wrneches and check every screw on the bow that you see. Do not negelct to check the module screws on the cams. Poosibly a module is loose.

Did you ever measure the axle to axle length and brace height like I told you to? If you've forgotten, axle to axle length is supposed to be 36". Brace height is supposed to be 7 1/4". If the axle to axle length is more than an inch longer than that, or brace height is more than a half inch lower, then you need to have the string/cable adjusted.
Knowing Hoyt's factory strings and cables, I'd bet they've done some creeping and that's why it's noisey.
