Awesome! Mine arrived very quickly as well. I highly recommend combining the install with an oil change... While I've done it without too much difficulty with the filter in place, it's really a breeze without it!

Loosen the middle bolt. Have someone sit on the bike. Don't know if having the feet on the ground or not makes a difference. If after torqueing the bolt back to specs the engine still hits the frame. Use a third guy to hold the bike up and have the guy sitting on the bike take his feet off the ground.
Sitting on the bike brings the engine back a little. Torqueing the bolt keeps the engine back there, in place. Now, if the rear shock is bad this may cause the engine to move to far forward. You will need to replace it.
How do I know? I made the installation video for Vibra-Technics Website.

On mine the front exhaust heat shield was hitting the frame. Check and see if you have a little nick/dent in the paint, on the frame tube.
I was told by Phil Bentley from Vibra-Technics to do this fix. It worked. This fix isn't in the video because Vibra-Technics put the video on their site, before I took the bike for a test ride.
Hope this helps.

Thanks for the tip. I am going to try this today but my front cylinder and pipe have a crap ton of room between them and the front frame rail. I just did an alignment at the top motor mount but didn't loosen the lower mounts and run the bike. I am going to try that. For the life of me I can't figure out where it's hitting at because everywhere looks like it has clearance. It can feel it in the pegs and something is definitely contacting in the rear or lower area.
I can't find any witness marks though yet

Rear mount might be shot. How many miles on it?
Before I changed the front mount (It only had 7200 miles on it) with a new OEM mount. The old mount was so bad, the engine was lying on the lower frame. I had no vibrations what so ever. When I first heard the banging sound with the old mount. I thought the steering neck/stem bearings wear loose. With more investigating, I found the front exhaust heat shield was hitting the frame when I hit bumps in the road. I put the new mount on and it stopped.
Phil e-mailed me. He saw my video on installing an OEM mount and asked me, if he sent me a Predator Mount would I make a installation video for him.
I installed the mount, took it for a ride and I got the engine exhaust shield hitting the frame again. I E-mailed him the problem and he gave me the fix I mentioned. Once again problem solved.
Your noise could be coming from anywhere. Check for misaligned or loose exhaust mounts at the front and rear. Check your shock mounts. You have to lift the rear off the ground, to check this. It doesn't hurt to check things that are not even related.
Hope this helps.
