been cold here and started the F800gs up today, turn the key, all the instrument gauges move and light up as normal. Hit the start button, one click of the starter, nothing, hit it again, fired right up. Then right after it was running, the gauges light up again and the tach and speedo go all the way through their sweep, then all is normal. Did this a few times with the same results. Thinking maybe battery, I turned it off and plugged in the battery tender, the charger showed full charge after about 10 seconds. Any ideas what would cause this?
