Stainless brake line and Change the caliper to a 4 pot Brembo then you get better brakes worth doing. Poke around my G/S link for how to machine the caliper. 2nd on Galfer green Pads, got mine from Happy Trails.
Get another rubber speedo boot for the tranny and fill it w/ grease. Not sure if it has on o-ring. look at Max BMW to see if there is one.
