Is there anyway of troubleshooting this? I have an 08 1098s with the full termi exhaust and ecu. I get a engine warning light and the air 4.1 code. Can this be cleared somehow? Is there something that was hooked up on the original system that is no longer in use with the full termi system? I bought the bike this way, any insight would be greatly appreciated. TIA.

An 848 manual says that "Air 4.1" is an "air temperature sensor error"

"Air temperature sensor
The sensor (1) is located on the right-hand side of the instrument panel and measures the external air
temperature:
the temperature signal is sent to the ECU integrated in the instrument panel for display and sent over
the CAN line to the engine ECU which uses it to make corrections to the map."


So I would guess you have a bad connection or a bad sensor.

I looked and it turns out I don't have the sensor at all. Thanks for your help, I will go buy one and plug it in.
