How does everyone attach their temperature sensor to Saito single cylinder gas engines? I find the gaps between the fins are too small to insert nuts to secure the sensor, and if I tap a hole in one of the more accessible/outer fins, the temperature reading is far from accurate.
This is how I have made it. I have shortened the metal lug of the sensor and used a M2 screw to fix it on the fin close to the spark plug. I’ve cut the thread directly into the fin. It's a Saito FG17. Works perfect.
