I got a charger for it and ican jump it if necessary.Question....is the battery image you posted in post #3 the actual battery that you have? Or one that is just similar?
I know their website says it will work for an EX, but a 14AH battery will definitely spin the starter better than the 12AH listed for that battery. As yorkie said, it will work for a great starting bike, but the extra amperage would be more helpful in less that perfect scenarios. i.e. sitting for a while, cold weather, etc.
Either way....7v cranking seems faulty. Can you jump from a car battery and see how the bike responds to a solid battery?
My Ducati is super sensitive to a healthy battery. So much so that I carry one of those portable batteries as insurance (call me paranoid). My point is that a healthy battery is needed for a bike to reliably start.
