Used original foam from packaging and made a "sandwich" with cardboard being the bread to keep it rigid. Used 2 velcro straps to wrap around to keep the "sandwich" together. It is then attached to the underside of the lid via velcro. The straps attach to 2 pieces affixed under the lid.
Wait a minute! I didn't get one! I got a 2011 Ultra Limited and the guy told me about it but it sure wasn't included on the bike! He did mention to not use shop air as it would How the seals and don't use a standard tire gauge as it would let the air out. So, does anyone know if the 2011's don't include the shock gauge?
