2014 RTW - Okay, so I'm taking off all the fairing panels necessary to get to the air cleaner. That's 13 plastic panels and about 30 screws. First of all I hope they didn't give the design engineer a raise for creating that idiocy. Anyway, some the screws have no shoulder (shank),some have a short shoulder (about 3 mm),some have a longer shoulder (about 6 mm) and a couple are extra long. The purpose and placement of the two extra long ones are obvious, but what about the rest of the 30 some screws? What is the factor that determines what type of screw goes where? They're all T25 torx with the same thread and same overall length.
The BMW parts micro-fiche images show what screws goes where. Unfortunately, when I took all 13 panels off, the screws utilized didn't match those fiche drawings and specs. As far as I know, this is the first time these panels have been off since new. So if the factory or dealership didn't follow the BMW specs for what screws went where, I'm hoping someone can help me with that. Where would you use each type of screw shoulder length?
