This thread cursed me, I was taking my r/65 and side car to a local antique car and bike show today, it's been on the tender since May. Fired right up, hit the brake baking up, flopped right to the bottom,from reservoir empty. And when I loaded the Sprint to bring to Florida a couple weeks ago, it's sat for 5 years, same thing, brake lever went to the bottom and stayed there. So I got on the Rocket, I had it out once since we got down here, didn't catch on the first try, battery too weak. I was afraid to try another bike, now, but my trusty Blackbird fired right up, sheesh.
Bless the internet, ordered a new battery before I finished my first beer at the show.
