I was all ready to yell water level until you ruined it for me.. Killjoy..
And, as much as I don't want to tell you this.. Your battery is close to being toast.. I know it's an expensive one, and it's only a year old, but my gut says you need to visit walmart and spend $49 for a new one..
I get 3 years out of my Walmart crap batterys, and I don't take them out of the bike for winter.. I'll toss the charger on them a couple times during the winter, but othe than that, they're abused, forgetten, and put away wet... And in the spring I put the key in, pull the choke, and the bikes starts without aid from a set of jumper cables...
Did I mention the batteries are cheap? (ok, cheaper than other batteries)
