    I have a 2010 990 Adv with only 1825 miles. Last night while in stop and go traffic the F1 light came on indicating a 54 warning lamp - secondary air valve problem. Bike seems to run fine. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>
    How serious do you think this is? Should I get it back to the dealer or do you think it’s something simple I could square away myself?<o:p></o:p>
    Any help would be appreciated!!! <o:p></o:p>
    Thanks, Scott<o:p></o:p>

    Secondary air valve does'nt affect at all the engine (except for some more backfiring if its always open).
    SAS blanking plates & a 13kOhm resistor (IIRC) are the way to go.

    Check all connectors near the air filter (front and back). Use the KTM HOW to see what things you are looking for. You don't have to remove the SAS, but should know where things are so you can check those connectors.

    Disable the SAS with tuneecu.
    remove the complete system and install some blanking plates.


    No more Fi problems and no more backfiring on decel

    And it's save weight:evil

    UPDATE:

    I have done the 15 min iddle reset, with the Fi ligh on. I have turn off th bike, turn on again and light had gone.

    I have riden for 35 min, and FI light has not come again. I have turned off the bike, and turn on again after 2 min, and FI light did not appear..

    Poltergeist? Mayne error was deleted with 15 min iddle trick?

    Does anyone know where the sas sensor or valve is? I want to clean it and make it water resistant.. I have cleaned the bikw and FI light has started to blink again.

    Thank you

    Lambda sensor of the front clinder. Put a resistor on the connector (forgot the right Ohm value) to check if the lambda is fried.
    If it keeps giving 17 then the wiring is faulty.

    Or get an OBD, TuneECU and disable them both right away!

    Turns out I had crimped the 02 sensor wire when I installed my crash bars.
