After I was caught in slow moving traffic through Copenhagen, with temperatures hitting 30 degrees celcius. I noticed that when the engine reached 110 DGC it began to decline in voltage on the display. Is that something that you goes have tried? It went from 13.9V to 12.2V and when out if the city it rose slowly to 13.9 again.
I wouldn't worry it will be because the fans kicked in to help cooling and you where stationary id be concerned if I'd didn't rise when moving. Crack on keep riding
