I have recently completed Ruta 40 in Argentina (Northwards), crossed Bolivia and came South through Chile clocking 12,000 Kms in six weeks. My beloved XTZ developed a sudden dislike for power between 4800 and 5100 RPM losing all power until 4800 rpm was achieved by the unrequired "govenor" A few sphincter clenching drops in power while accelerating/overtaking made me visit the main dealer in Santiago. No fault could be found. I have recently experienced the loss of all electrics too from rainwater ingress. Not too worried about the latter but the former seems mysterious. I would appreciate any suggestions as Yamaha are not well represented on the Falkland Islands where I live.
