Ok not yet.. I'm looking for ideas on how to set up the air box for sand (never ridden the dunes yet) as our intake scoops will scoop sand if you put er down in the dunes I am really meticulous when it comes to my bike and I want NO sand to get past the filter besides air filter maintenance and grease on the base as well as the PC prefilters have anyone made any mods to the intake shrouds? Here's an idea let me hear your thoughts and input. Drill some holes under to allow sand to drain?? I got some quick release 1/4 turn clips for my air box so I guess I could just pop it off real quick and shake the sand out..
