In this pic you can see the engine temperature thermistor wiring on the lower left with the plastic around it for insulation while experimenting with resistors. The brass sensor itself is mostly obscured by the valve cover but it's right at the end of the fat white wire which is actually heat insulation. Very easy to unplug and unscrew with a 10mm wrench. Here is a link to a PDF manual for the EFI system used on Lifan motorcycles.
