I hadn't riden my bike for two months. Started it up and rode today for like 3o minutes of trail riding followed by 5 miles of freeway. Idled the bike for 5 minutes and then after washing the summer dust off of it tried to start the bike to return it to the garage and it wouldn't turn over. Trickle charged it over night, and have a green light on the battery tender. Do I have a bad battery or does it just need to be run for like a long time? An hour or more?
