Ok, so with the original battery I can stand at the back of the bike (not behind) to one side and the warning doesnt come up, but if I lift my arm, key in hand, the key goes out of range. Then I hold the key at the back of the luggage rack, then the rear of the passenger seat, and then the rear of the driver's seat. Warning goes off at the rear of the drivers seat.
New battery fitted and repeat.... standing at the back with arm up, still in range. One step away from bike.... out of range, so an improvement. Key comes back in range at the rear of the passenger seat, so again an improvement. Hopefully that solves the problem.
I had two orange keys showing on the dash, alterating between one key and two keys, one with a "?" next to it. Cant remember if that was the case during the ride? Better read the manual I suppose
Still wondering about the warning the GS gets... would have thought the RT would have the same....
