I have a Magura Clutch on my 2000 - yz426 and is seemed like it was grabbing real jittery when engaging. I was checking it out and found that the rod that connects to the clutch arm was bent. So I straightened it out and had to bleed the system. (Great posts for doing that on tt) I noticed that the rod that got bent now has residue on it each time it is pulled. I am wondering if there is a seal or gasket that may have blown out. Is there a rebuild kit for them? Anyone have any experience on this?
