Hey guys I am a new rider and just got a 2000 katana 600. I lost my balance while driving it up the driveway so I do my best to gently laid it down(My heart is bleeding, can't believed that I laid it down). I hit the kill switch and keep it upright. I took the seat off so the air can flow freely and after a few tries the bike did starts back up again. After two hours my friend wants to see the bike but it won't start. We jump start it and it did work; however, after a hour we tried without the cables and it won't start. Is there a problem with the battery?
