Intake Air Temperature (IAT).
The purpose of the IAT sensor is for the Engine Control Module (ECM) to correct for air density changes when ambient air temperature changes.
The colder the air the more dense it is, therefore more oxygen content, so the ECM make a correction to add a bit more fuel to the basic fuel injection calculation.
The ECM correction factor for the IAT is negligible, so modifying the IAT output to trick the ECM for more power is not worth it.
Having said that, the Engine Coolant Temperature (ECT) sensor has more correction value percentage (compared to the IAT) to the basic fuel injection calculation, since the CB1100 does not have a radiator, the ECM uses the Engine Oil Temperature (EOT) sensor instead to compensate from a cold to a fully warm up engine.
The EOT sensor uses the same type of Negative Thermal Coefficient (NTC) thermistor as the IAT, meaning when the engine is hot, her resistance drops.
(At 20 degrees celsius it has a resistance of 2.2 kilo ohm and when warmed to 28 degrees the resistance decreases to 2 kilo ohm.)

Basic Fuel Injection Calculation:
For the ECM to calculate the basic fuel output, it requires signals from the Manifold Absolute Pressure (MAP) sensor and Engine RPM (NE) then it add the correction factors such as EOT, IAT ,Ox and so on.

Hope this help

By the way, it is a very interesting description, I learned a lot about temperature.
