My surron keeps going into slow mode after about 20 min of riding sometimes less. The error code reads as "motor over temp error" The motor doesn't feel warm and I was advised to just short the thermo coupler wires coming from the motor to bypass this sensor. This seemed to work for a little while but now it drops back into slow mode all the time again and shows the same motor temp error. Any ideas of what could cause this? Mahalo!
