2020 XC800. 2018 pro s switchback 600.
2020 xc 800 runs around 113 to 118 degrees coolant temp. Will go to 130 if left to idle. At WOT will cut power at about 70 mph. Bad thermostat,temp sender or what else? My 600 runs 124 degrees all day.

All the redesigned motors since 2018 run lower temps, cant go by what the older 600 runs. 800HO got a new head design & stat in 2018 and they run more like what you are seeing.
Ran ny 850 all day today between 99 and 110.

Did you change out the electrical relays yet? The relay that runs the power valves could be shot.
