Hi All-

Just picked up an Ď81 R65 with relatively low miles but needs a lot of work. The bike has twin front rotors, something I thought wasnít available on the R65, but rather on the LS. So perhaps that is the modification as it appears to be stock equipment complete with Brembo gear. The master cylinder is shot, so trying to source a new one. Would anyone be able to tell me the size of m/c needed per mmís? Also, suggestion on where to source this part?

Thank you!
