The battery would be my #1 suspect, as well. Sounds mighty like a dead cell. Take it to a parts store and have it tested, and when they tell you it's shot -- new battery.

As long as a bike has a 12-volt system -- which most do, these days-- you can jump it with a car. But be cautious. The car battery has enough juice to do it without the car running. And, as most car jumper cables have pretty large clamps, be extra careful that you're not shorting to the frame or between the clamps.
