Hi all - took my DL-1 (the '70) out for a spin this past weekend, and noticed a brake problem that gradually got worse. Right at the first pivot on the handlebars, the rear brake rod seems to have a loose connection. I can't see any clear way to adjust or tighten this. Any advise? Thanks in advance. Here's a video of what I'm talking about
