Installed mine last week and let me just say this....if you don't go out and buy one of these, you're an idiot. My wobble is absolutely gone. And I mean gone.

Are you using a torque wrench?
Just common sense, but I'd tighten the thing down to spec,, then run the engine and check torque spec after running. Then I'd check torque spec again a week or two later.
Thats the procedure I used but I remembered the Harley manual said to loosen mounting bolts and run engine to let mount find its center. Just wondering if that applied to this mount.
When I first installed mine, I torqued everything to spec before running the bike. I've had my Predator in and out a couple of times now for various reasons, and I've taken some time to really attempt chasing and rectifying excessive vibration. In the process of doing this, I've swapped my OEM mount back in for a spell to isolate something, I've run the Predator with the stabilizer link disconnected, and I've played with the installation of the mount a bit (as well as stuff that has nothing to do with the front mount at all). I've definitely experienced more precise control while cornering, and less "rear steer" feel with the Predator mount. However, It hasn't always resulted in less vibes reaching me as compared with the OEM mount. I currently seem to have arrived at an overall setup that handles very nicely, and is relatively vibration free at most RPMs, and is glass-smooth in some ranges.
After a rambling intro, I'll answer your question: My vibrations reduced noticeably after I reinstalled the predator in the following manner:
1. Place a stand or jack under the bike that will allow the bike to stand vertically, but with both wheels on the ground.
2. Install the Predator and all of the hardware hand tight.
3. Torque the mount to engine and mount to frame bolts to spec. Leave the center bolt completely loose but with the head within the mount (you may not be able to feed the bolt into the mount after the other bolts are tight).
4. Start the engine. let it idle, blip the throttle, hold it constant around 2500 for a few moments, bring it back to idle.
5. Tighten the center bolt fully while the bike is idling.
All of our vibration issues seem to be a little bit different, but this worked for me. The difference in vibration was noticeable between my initial install and the reinstall with the above method.
Note: It's MUCH easier to install the Predator without the oil filter in place, but my 3/8 ratchet drive will fit under the filter with a relatively short allen key socket. Removing it was tight enough that it dimpled the bottom of the filter slightly, but it can be done.
