The temperatures on my new FXS while sitting the the garage unplugged are:
86 F Ambient from thermometer
109 F Motor
93 F Battery
88 F Controller
It was not recently ridden. Should I be concerned that the motor temperature is so far off? I'm trying to figure out if this will impact my riding, but have found the owner's manual lacking in information (or else I'm not looking in the right place. It qualitatively describes the thermal strategy, but the only quantitative information for high temperature are as follows:
110 F battery temperature - reduced charge current
122 F battery temperature - no charging
140 F battery temperature - no operation
Where can I find the values for the thermal limits? I tried searching, but admittedly didn't read every post in the forum.
EDIT:
From the article Richard230 just linked to, the thermal limit for the motor is at 284 F with a warning at 212 F. I'm still curious what the limits are for the battery and controller and under what conditions those might be more limiting.

The reported temperature at rest for the motor is way off for most people. Mine too. The controller and battery readings on mine seem close enough to reality, it's just the motor that is off. It has not caused problems while riding. I have the '15 SR (with the older, non IPM motor) and have gotten the warning light to come-up only once so far and it did not actually get to a point where power was reduced - I was riding very fast, way faster than I should have on a public road, and the weather was hot too. I do not think it will ever come on in "normal" commuting for me.
It is unclear if the motor temp. readings are more accurate in operation, when it is actually hot, vs. when it is cool in the garage...

How or what did you use to measure the component temperatures with?
If it's an IR signature then surface type (and color) will affect the reading.

Temperatures are as reported by the app. Since the bike was sitting in the garage unplugged, the difference from ambient is error in the sensor calibration.
