Just finished a build using a cb750a 1978 motor. Chose to use a 1981 cb750c frame so I wouldn´t have to pull the motor if it needs Head work...and it did!. Built the bike over an 18 month time frame with my son. We both like the old Shelby Cobra paint scheme and the hotrod look so that´s what we went with. I chose to use a jockey shift instead of foot controls to add to the hotrod feel. I will post a few pictures when I can.
