right now the thermostat reads the water temp coming out of the radiator. I think what you're referring to is relocating the thermostat from that side of a radiator to inline with the hose on the other side of the bike reading the water temp coming out of the bike where it will be hotter. This enables the fan to come on sooner than normal. You would just put a bung plug where you took the sensor out of the radiator.
