Went riding this weekend and while riding off camber in one difficult spot when I should have give it gas i let off and rolled the Sportsman. The only damage done was it will no longer start off the Battery but the Pull start worked on the first pull bike runs fine,looks fine. I guess what I want to know is can you kill a battery cell by turning one upside down. Any info would be appreciated. Also rolled it one more time before going home slight sprained wrist but mostly only my pride is hurt and I was laughing so hard after it happened could bareley tell my wrist hurt at all. It was still a great day of riding.
