My son just picked up a '74 R90/6. It is not running and we haven't started working on it yet. I have a '76 R90/6. The question: My '76 has the conventional looking electric control switches, i.e., rockers for the turn signals, paddle for the high beam, etc. His '74 has totally different controls. Each side has a flipper switch that apparently you can push in. Since it isn't up and running and doesn't even have a battery in it yet I can't tell what is what. I'm sure if I spent all night google-ing it I could find the answer but....anyone wanna clue me in?
