    78 GS750 Warped Front Rotor

    I've been having front brake issues for a while and narrowed the problem to a warped rotor. The previous owner installed a single disc 2000 CBR1100 Blackbird rotor in place of the stock rotors. I've been looking for replacements but I don't know a whole lot about proper fitment of aftermarket rotors. Can anyone who has upgraded give me some advice please? Thanks a lot!

    Honda Blackbird rotors should be no different than other rotors, how bout try a local machine shop truing it back up.

      Lets have some pictures of the setup... It possibly has a conversion bracket on it and a hub spacer. Usually the problem isn't the rotor with the floating rotors it's junk caught between the rotor / spacer / hub or where the holes have been drilled out on the rotor & the back side has not been cleaned up.
