I just bought this 91 kawasaki 550Sx. The guy started it with another battery he had and then I took it home and tried to start it using a bigger battery that was for a wave runner, then I went and bought the same battery my buddie has in is 550 and all it does is makes a click when I try to start it. So then we tried using his battery and it does the same thing. Is my starter bad? Please help me I am new to this sport. I am familiar with dirt bikes but not to the pwc's yet.
