I keep my battery on a trickle charger when the bike isnt being used. Lately when I unplug it and try to start the bike its like the battery is week. Its hard to turn the engine over but when it does it starts. The charging system seems ok while I'm riding cuz the volt meter goes to 14 when I have power on and goes back down to 10 to 12 when power is off. Everything seems ok when running just weird when starting. I just got the battery about a month ago. Maybe something wrong with the battery? It charges acording to the lights on the charger. I get a full 12 volts with a meter. Starter going bad? I'm baffeled. Any opinions? Thanks in advance.
