I have a dead battery on my WR and have been kicking it to start it for a month or so. I think I killed the battery in the spring as the bike was hard to start in the cold. A battery tender wont keep it charged either. Yesterday I was riding, and it was a long slow descent (low revs, no charge to the battery?) and the bike started regularly backfiring, then it just died. Does anyone know if this can just be a result of a fubared battery, or is it something different. Bike would not start at the end of the ride.
