OK...riding tight trails this weekend, about 75 degrees ambient temp. The bike dies while hitting the throttle in an uphill corner. After I pull it back onto the trail, I hit the button and the battery is dead, so I begin kick starting it. It would not start after several kicks. Thought maybe it had overheated, so as a last resort I drained the carb bowl and it started first kick. This happened several times throughout the weekend. Bike dies (or I just shut it off), starter won't turn over, won't kick start until I drain the carb bowl, then kicks right over. Got back to camp, and checked/cleaned the battery connections. They looked pretty corroded. After cleaning, the starter worked fine. But why would I have to drain the carb bowl to get it to kick start? Thanks for any help.
