I purchased a batter from batteries plus 2x and returned both because it didnt do anything. Also, it doesnt cost anything to have your battery tested. I would definately do that first. Mine tested at about 20% higher rating then stock CCA. It was very strange. I bought a battery still and tried it, but no change. I did find it was the starter relay. It was running about .5 amps all the time. So my battery would just drain constantly. The new one has worked fine so far. I rode for a few hours yesterday and i haven't had any problems. I have also let the bike sit for a day or two and then pop the trickle charger on it and it goes right to full charge.

Also, i would recommend batteries plus for the testing. They dont charge and they have good rates. I got my battery for 44 bucks there which was 10 bucks less then they normally charge. The guy liked me i guess

Good luck!
