I have a K1600GT and replaced the top brake line with a brake line from a GTL. I’m having difficulty getting the screw that holds the top brake line to the steering head (where it connects to the Lowe brake line to the modulated) installed. My fingers are two big and the angles to tight. I have dropped the screw several times (like a dozen times). The BMW manual has nothing on replacing that brake line. It only has instructions for replacing the lower front brake line to the modulator (at least that all I have found). Anyone replaced the upper line and figured out a way to get the screw back in, or is removing everything, including the gas tank for access the solution. Thanks for any help.
