Also, still want to use the front brake switch splitter, can I reuse mine and run 2 separate brake lines of the bottom to each caliper?
Single disk rotor is thicker than dual disk rotor, so use two matching rotors.
Yeah, you can use that damn splitter if you want, but I use a later model master cylinder that has a brake light switch bolted on. and two lines from the master cylinder, one to each caliper. Braided stainless steel of course.
ZX11, ZG1000 and lots of others use the same master cylinder, rectangular in shape with hole for mirror and it's own brake light switch. And rebuild kits are easily found.
I have 1980 KZ1000 rotors with 1983 GPz calipers and a 96 GPz1100 (same as ZX11, etc) master cylinder on my 750 twin. The master cylinder is a 15mm, and I can lock the front wheel easily with two fingers. I have no inclination at all to install a 1/2" master cylinder, as then I would have to devote to much attention to avoid locking the wheel, at a time when I have no attention to spare.
In an actual comparison between my 79 750 twin and a 84 750 Turbo (GPZ), my bike stopped 30' shorter than the 750 Turbo. And that's a lot!
YMMV, I just know what works for me.
