where the heck did you find a black or gray pool noodle!?? Only pool noodles I see are neon colors, blue, green, pink etc. I'm thinking some AC insulation like this would work on those forks.

And yeah at $125 a pop I can deal with it too. I wish I could mount the racks higher like moombadaze, but the combination of my Z5 rack and Rev 10s wont allow it.
