Hi, I've just bought my first Yamaha 1300, 2008 model. I'm only a fine weather user. I would appreciate if anyone could help me with some quesions regarding the Optimate 4 battery charger which I am just about to buy. My quesion is can I charge the battery using the adapter in the small compartment on the left upper fairing. I always call these adapters cigarette lighter port but that's not what it is. Any help on this would be appreciated. Also, where's the battery and how can I access it as the previous owner never gave me the owners manual.
