The volume of brake fluid needed to actuate the calipers is very small. Most important is matching the proper master to the calipers used.
I think I mentioned before your calling Magnum Shielding. They have a solution for most anything.
I can't over state the quality of their products. I bought a replacement set for my '08 xl1200r when I upgraded to xr calipers.
I have a set of throttle cables and a new clutch cable from them. Just waiting for the heat to moderate in the early evening to do a oil change and swap in the new parts.
