Thanks for the link. They had news, although not good. Turns out that the rotor is not the problem, its the relocator bracket. Matt at procycle told me that no one is making one for the KX5 any year before 1994.
So, I asked about seeking out a machinist to build me one. He told me that it would be tricky at best, because the caliper doesn't actually bolt on? it floats on pins. Funny, thats not how I saw it when I took it apart.
Anywhoo, I think I have a solution to that problem, the floaty bit anyway- I'll have one built, but to support a radial style caliper.
So lets hear some input- love to hear from anyone with experience with problems like this, and any machinists who could help.
Thanks-
Dodd
