So I'm the owner of that stranded Ural. I feel
terrible for leaving her there all this time. Here's the story, which hopefully answers some of your questions.
I ride the Ural all year. In the winter I ride in the city, unless it's icy.
That particular day
was cold, but with a full-face helmet, long johns, and a parka, you don't really feel the chill for rides under 20 minutes.
My band plays a bi-monthly gig at C'est What, at the corner of Church and Front. When I got there around 2:30pm the weather was fine. When I left the gig at around 6:30pm, the sun had set and the temperature had dropped dramatically.
I started the Ural just fine. Giving it gas, though, stalled it. It would idle fine, but wouldn't move. I figured I would leave it there for the night and come back when the weather was warmer and I could either (1) drive it home or (2) dismantle the carb and inspect the float needle, etc.
Then we had that lovely cold front and snow that didn't abate for a few weeks. I went back to check on her and try and start her up, but no go. She's frozen.
I contacted Ken (kneedragger88) to get her towed and serviced, which will happen this week, I hope.
I feel bad for leaving the motorcycle out in this weather. Overnight it's typically stored in a garage, and outside during the day while at work, etc.
My wife loves riding in it. It's extremely convenient for carrying groceries / furniture / beach supplies / bags, etc. The third wheel helps a lot with stability. When it's engaged, it's quite nice to ride in the snow, especially in the back-alley leading to our house.
Just saw this thread now. Here she is in nicer weather:
