Thanks everyone...I'm excited for better brakes. We measure one and it's definitely warped slightly (I forget the number) but I have a CB750 expert who is an airplane mechanic helping me finally sort this bike out. He says it's warped, it's warped

Also yes, I already have double discs...I used the GL bolts and had the heads made shorter to clear. The speedo drive uses two small pins that go into small hole in my hub. It's all in my build thread...

If Bill says it's warped, it's warped.
