Wow, one year for some of you is nuts ! I'm at almost 2.5 years and mine still works. However, i have been having issues lately when starting. Not with getting it started, but idling once it has started. I have to give it some throttle. I tried setting the thing in tuneecu that sets the stepper motor and tps but none of that worked. Wonder if it's my time, which is why i asked about alternatives to the stock battery.By the way, ebay has batteries with the same number but without the Yuasa logo and say they are for other bikes like yamaha. i wonder if thats the exact same battery or could the number refer to the specs but not the physical size and therefore they might not fit?
