Having issue with my 2011 Repsol Fireblade where bike was sitting on battery trickle charger for a month or so. Disconnected it and wouldn't turn over and battery seemed flat. Changed battery for new one and charged it up and put in bike and was very slow to turn over and eventually stopped turning over like battery was flat again. Stuck charger on for 10 mins and bike fired up so left it running for a wee while and stopped it. Tried to start again and it was like battery flat again. Any ideas?
