Tried to crank the bike up last week...no go, put the battery tender on it for 2 days...no go...but close, looked up when I purchased the last battery (big crank)...almost 6 years ago!!!
Went and ordered a new Deka battery cuz it was the same but different and heard good things about them. Arrives next week...
In the meantime I changed the oil and filter, took the battery off the tender and reinstalled just to see...took a couple tries but fired right up!
Multimeter shows 13.5 volts while running, 12.7 when not...
Oh well, probably time for a new battery anyways...
