Ok so I hooked the jumper pack and my bike started on both cylinders after I realized both spark plugs were loose. It is running ok with the jumper pack on it. Its got a back fire with a quick blurp of the throttle but I think that's because it was getting hot. As soon as I disconnect the jumper pack it starts to stumble then stall. Any ideas before I go grab a new battery I think it is still the original on for 08.
