    HAHAHA now that is ironic.

    Burn some fuel off and let us know if it goes away. I think mine took about 20 miles to drop the level far enough.

    BTW, Buells with a stock ECM have a torque drop between 3200 and 3500 rpms depending on the engine. You might be feeling that.
    American Sport Bike did a huge muffler Dyno comparison years ago. Attached are 2 Dyno's of stock setups. XB9 and an XB12 Dyno

    Gee thanks Cooter, now this is what I'm going to think of when asking questions on the forum...

    You, Lunatic, Silver, Lusiphur and the other senior members can sort out who is who, for some reason I imagine Lunatic as the red one.


    Lu, I will have to check again after I fuel up but I haven't noticed the scary bubbling lately, may have been a one-off.

    I doubt it is the torque drop, it just feels like it pulses when under steady load around 3-3500 and it can get stumbly in the idle and lower revs. If I roll into it, its smooth.

    Thanks Coots, now all I can think of is that the OP has one of those diver/treasure chest aquarium things in his fuel tank.

    Normally, I am the little blue fish in the upper left.
    Quietly lurking, but give me a topic I am passionate about and I become the big mouth in the middle.
