Good man. Yeah, in the pics, they look like the stock black rubber mounts. I'm sure the vibration/shaking sucks (I personally don't own poly mounts). I've heard some say it's not that bad, while others say it's pretty damn unnerving. I imagine it's liveable running the poly mounts, but it probably gets pretty rough, when the balance shafts are removed from the motor.

At least you have a proper setup for that big snail. Rep for you.
