Hey, I am new here. I am trying to get an 81 GS550L running that sat for I don't know how man years. Most things come apart for cleaning or replacement, but the choke cable is frozen and I can't get it off of the bike. I detached it from the carb, but I cannot get it to move from between the handlebars. I loosened the round nuts that seem to hold it there. Am I missing something? Anybody got any ideas?
