I had the same question and asked my service guy. The air filter is under the black plastic covers/air intakes just below the front of the gas tank. I think you can just remove a cover and slide it out.
The ECU is under the tank someplace, but I have no idea how to get the tank off. It clearly is a harder proposition than my old monster, which just had one latch to lift up.
BTW, where did you get your Termis?
