I've had a 986-504-893-00 (Side Cover Seal) held on by tape for awhile after an "event." Decided to pop the 986-504-393-00 (Side Cover) off and see what I could do. Cleaned it up and fixed one of the rubber nibs holding it in place that was sheared off but still present. Push pins are taking care of two other missing nibs (I know, I'm a genius).
Moved to the other side and found that the side cover seal was missing altogether (no wonder the aerodynamics seemed off!). Popped the Side Cover off, removed 6 grams of dirt (sprung mass), cleaned it, replaced and ready to see what the weight reduction will do to my power to weight ratio!
