My 2014 Speed Triple R with 18K miles occasionally refuses to restart after a short stop, i.e. a stop for gas, or if the engine is accidentally killed pulling away from a stop light. It will turn over once or twice, repeatedly but will not immediately fire up...it will restart given a five minute or so break. The battery is three years old and is always on a tender in-between rides. Battery voltage was 12.78 a couple of hours after today's ride. If the stop is longer than just a few minutes, i.e. for lunch, the bike will start right up. Anyone have an idea of what's going on?
