Answer
First, its not a good idea to start your bike like that in the winter. When a motor cools it draws moisture. When you start it you have to let it run long enough to drive the moisture out. At around 30 degrees that would take about 20 minutes of sitting there idleing. Your better off starting the bike and shuting the petcock, let it run and let the carb go dry. Put a battery tender on the battery..
How do you know your cylinder is not firing? The only way the cylinder would not get any fuel is if the piston was not moving up or down, a valve is stuc open or the intake is plugged.
