Hey there all, I have a 2003 Kawasaki Ninja EX250 and recently my motorcycle started to have problems starting. I believe the problem to be the battery. I popped the seat and the battery is a tiny 7lb one. I tried to go to walmart and advanced auto zone and also looked online, but it doesn't seem like anyone carries this type of battery anymore? Does anyone know where I can find this type of battery or if I can use another battery type that would also work?
