I meant the reservoir. The pipe doesn't make direct contact with reservoir but the mounting bracket itself which i is large enough that the mid pipe doesn't transfer enough heat over to the reservoir to melt it. Ive ridden 2000 miles like this, and have not had any issues (not to say that I wont, or this is the right way to do it)

The quick, easy fix is to get a $15 Brembo rear reservoir, or the more expensive G-Craft piece which mounts right to the master, and eliminates the worry.

As far as M4, I have no direct experience with them, and from what I hear they are great for the Zuks. I have not heard great information about them as far as the blades go though.
