I have a 2010 Alien Nemesis and am having sound issues. First of all I was in a hurry and put a cheap string on it (my fault). As the string stretches I have it twisted to try to keep in in spec (34" ATA). This last time I found something odd. When I measured my ATA I got 34 1/16" (acceptable for now). When I turned the bow over and measured again (on a hunch) I got 34 3/16" (unacceptable). I remeasured several times and still get 1/8" difference in ATA from one side of the bow to the other. Is this normal? If not what can cause this?

Thanks!

Its completely normal to have a small amount of ATA difference from one side to another on any bow with a cable guard. Its just one of the effects of pulling the cables off to one side to get arrow clearance.

So should I tune to 33 15/16" on one side and 34 1/16" on the other? I am going to a better string after the end of the season but for now I would just like to quiet it down.

Isn't your bow a Hybrix cam bow? If so there is no way to change cam lean/limb twist. Maybe an offset cable guide rod would help a little but you are very limited to what you can do with a Hybrix cam bow.

are your cams in time with each other and are the cables routed correctly?

Cams seem to be perfectly in time, cables routed correctly and it laser-tuned on the money. Other than being loud it shoots like a dream. I am getting 285 fps at 27" DL set at 68 lbs shooting 26.5" Ted Nugent Goldtips.

That is kind of what I was thinking. The pockets look good, pads seem even. I am going to check my measurements again tonight since I don't remember which side was long. I might be able to put an offset cable guide rod on and "torque" it a little more (if that is the long side).

How close to the string is your STS? Most guys say about a credit card away. Could add some cat whiskers, which kills most all string vibrations, and maybe put some limb savers on the limbs. Ought to quiet her down. :)

I keep my string about 1/16" away from my STS (just enough to see daylight). I have limbsavers on it but have not tried anything on the string yet. It doesn't really sound like string vibration (more of a sharp "thump") but I am more than willing to try some whiskers or monkeytails. Will try to keep you posted.

Thanks

I think this sounds a lot like mine sounds. I'm fighting a STS that doesn't stay tight and when it gets loose it makes this kind of sound. When it starts making that sound I can grab the (offset) STS rod and see it move around.

Check to be sure the end of the STS rod is not butted against your stabilizer. Also - you can put a piece of foam in between the two, this seems to knock down some noise also.
With my FireCat - it was quietest with the bumper just a hair away from the string at rest, however with the Nemesis, AX and AZ - they are the quietest with the
string right up against the bumper at rest.
Actually on my X's and Z I have the bumper turned so the slot is 90 degrees to the string rather than the string hitting in the slot.
One way to find out if the STS is the issue is to just take it off and shoot to see if that eliminates the noise.
Another thing may be - have you shot other bows with the STS? They do produce a thunk when you shoot.
And have you had someone else shoot it while you stood 5ys or so away and listened?

mine makes a noise like you are discribeing ! i thought it was a bad limb, so i sent it in to martin they checked it out and said it was ok . when i got it back i made new string & cables for it and put string sliencers on it. it seems to me the more i shoot it the quiter it is. im not going to worrie about it is a very accurate & fast bow & i love shooting it.
good luck on yours!
