    there's a reason your AFV value is all over the map. ask the ecm gurus why. i'm not one of them.
    O2 sensor on the way to death row.
    pull your front spark plug and check. betting it's slightly fuel-soaked and sooty black in color. that will confirm overly "rich" mixture.
    check for historical fault codes....see list below. betting #13 is revealed.
    vacuum ports have no "interface" whatsoever with the fuel system and/or an injector. to clean an injector it would have to either see a cleaning agent thru the fuel delivery side or be removed and physically cleaned.
    your tps unit might be dying. my check suggestion above will reveal.

    11 Throttle position sensor
    13 Oxygen sensor
    14 Engine temperature sensor
    15 Intake air temperature sensor
    16 Battery voltage
    21 Interactive muffler control (XB12 only)
    23 Front fuell injector
    24 Front ignition coil
    25 Rear ignition coil
    32 Rear fuell injector
    33 Fuel pump
    35 Tachometer
    36 Cooling fan
    44 Bank angle sensor
    52, 53, 54, 55 ECM failure
    56 Cam sync failure

    I agree with the guys thinking you need to check the intake seals

    I have new Genuine James Blue seals on the way.

    I may also do the O2 sensor.

    I found on badweather that there is a Bosch replacement that works also, any thoughts on that? The O2 sensor is a regular stock at autozone and is $20.00 vs $50.00 for OEM

    all of the O2 sensors i've listed below cross over to the stock XB O2 sensor and are inexpensive. the bosch for example is under $20. if you can't locate one i keep the bosch in stock and will send you one.

    02 sensor for buell from GM delco
    GM part #25162693
    and that crosses to an AC-Delco AFS20.




    Bosch 12014

    GM OEM= 8990469 superseded to 25162693

    NTK= 21002

    Airtex= 553071

    Denso= 234-1001

    Walker= 250-21001

    SNG= SN1-15
