I parked my CBR sometime around the beginning of November not knowing that it would be sitting for the winter. Soon after bad weather came so I covered the bike. A month or so later I tried to start it and the battery died. I charged the battery and the same thing happened. It died before the bike ever got started. Hoping that the battery just went bad, I bought a new one. Now it's the same story with a new battery. Anyone have suggestions? I thought of draining the carbs but haven't done so yet.
