The battery in my '04 WR 450f has a very hard time starting the bike. It cranks for about a second and then just clicks. I have heard of Battery Tenders and batteries that have more cranking amps, but I am not sure which is the right way to go. I have done a search, but have not found a satisfactory answer. I was at the track last week and a number of people said how much they wanted a magic button. I had to smile as I began to kick start the bike. I need help!
