There are some very capable head mechanics out there who discovered their passion for the old Hondas, decided to specialize in them, and opened their own shops. While they are often younger than the bikes they work on, they are not only capable, but they possess real expertise. Maintenance and repair is not all they do very well, but they often offer full restorations and performance improvements of any kind. Most of them have their own machine shop and dyno. It’s just a matter of finding these dealers. This forum would probably be a good place to inquire about competent and passionate shops. Most likely, their owners are members here. I like what they do in the German CB Four forum: they simply list them on their web site. Moreover, not every mechanic in the 70s was competent and bad shops were not entirely unheard of. And as a final thought: You don't have to be 200 years old either to have expertise on the subject of the Civil War.
Furthermore, you probably won’t find experienced old-timers in Spain (Clasico is located in Madrid) because I simply have never seen a Japanese motorcycle in the 70s in Spain. Either, their import was not permitted, or they must have been taxed so heavily that no one bought one. I recall having seen lots of BMWs and all sorts of Italian bikes along with a Spanish Sanglas occasionally. During my frequent travels, I have never seen a Honda motorcycle dealership in Spain in the 70s or even early 80s.
