2022 KTM 250SXF with QS 138 motor and overheating EM260S (70 degree C)

In the previous RUclips the bike stopped due to overheating Controller. It appears to be set at 70 Degree C, and it cannot be adjusted , as far as I know. I am putting a water cooler on it this week. After these 2 laps, it went from 55 Degrees C to 66 degrees C. Todays temperature was in the high 80'S F
