I was riding my 2004 ltz400 the other day and i was riding it and it just died, and when i went to go start it up again it made a clicking sound. I charged the battery and it says open cell or sulfated. When i bump start it, it will start right up, no problem. I dont know what would make this happen, but i dont wanna bring it to the shop and pay $65 an hour, and find out its something stupid. I also dont want to waste money and find out thats not the part i need. Please help ! thanks !
