I took off my Tupperware for the first time (new 06 7k miles) and found the same dirt as the first pic in this post: https://www.st-owners.com/forums/showthread.php?t=45076
I also attributed it to road dirt/riding in the rain. I cleaned it all off and since running the bike a few times there is oil at the weep hole! It's not running out yet but you can see it at the opening. I twirled a small piece of paper towel into the hole and definitely got oil, not coolant.
So now what??
You can remove your right side plastic bumper cover and look with a flashlight and see your weep hole. How's yours look?
