Motorcycle Repair: valve adjustment, vintage japanese motorcycle, honda cm

Question
I have a 1981 Honda cm 400cc and was wondering what the valves were supposed to be set at

Answer
I believe the clearance is 0.005", but it is best to refer to a proper service manual to make sure. It will also detail all the procedures for maintaining and repairing the bike.
