Galfer did actually make a few brake line sets for the the Gen II, I have a set on my bike. The entire set for the Gen II FJR is if I recall about 13 different line sets and the task level is pretty high for the install. I was one of the gunie pigs for distribution of the sets and I think they only made 2 maybe 3 sets total. For a do it yourselfer it is a fairley demading level of effort. The area that is particularly difficult is all the line replacements back at the ABS module.
I passed along the difficulties along with a problem of securing the area torwards the front of the frame where it transitions to hardlines. Additionally bleeding the entire assembly was fairly time consuming also do to the extensive amout of volume with all the lines.
This maybe some of the reasons why Galfer has chosen not to offer the set for this GB if they do at all, I'm not sure.
I have the rotors too, front and back, look way cool and work well. They seem to be holding up very well and there seems to be no addtional wear to the pads, I say this because I primarily brake with the fronts only and the right front caliper shows very little difference in pad wear from the set associated with the front brakes and the set of pads tied to the rear brake set. I would guess I have about 4 to 5000 miles on the components.
