this show was either from the 80's or very early 90's. we used to watch it in school and i later saw it on pbs, so it's probably not very well known. i think it was called story lords or something like that. it was about this boy who was the apprentice to this guy. and there was a villian who rode a motorcycle and wore lots of leather and metal and stuff. the boy and the guy would try to figure out secret messages or words or something.
