It seems like a good place to get batteres as there's a wide selection and good price. I would just change it. It's not worth the hassle of being stranded for a small amount.
I've heard that you can jumpstart a motorcycle in 2nd gear. Not sure if this applies to fuel injected ones. Maybe someone here can confirm?
