    Is it coughing through the intake? That's a sign of a lean condition. If you have an intake leak the ECM should compensate for it with factory settings. Step 1 is to check your AFV and then act...

    Actually, in open loop the ECM will not correct for a lean or rich condition. However, the O2 sensor can still be active to inform you about sensed lean condition with a CEL. That way you can do...

    Why tune to 14.7 to accommodate a narrow band O2 sensor? It will run cooler and have better throttle response at about 14.2. Plus, those sensors are not the most trust worthy. I only keep the O2...

    Instead of running CL for economy, I suggest changing your AFR targets in the cruise range to about 14.2. If you run CL you run the risk of the ECM leaning everything out.

    The FP10153 regulator you listed is the same as stock. If you want 58 PSI (4 bar) the Walbro 135-22 is an option.

    Technically you can, but your pump is already regulated by a mechanical fuel pressure regulator so the sensor data would only be good to look at. Adding another O2 sensor does nothing for you...

    The first step is always to check the AFV to see what the ECM has adjusted itself to, then act accordingly. It's probably running lean like most Buells. Don't change any parts until you've done...

    If your ECM had the "Uly" problem you would see a laundry list of stored faults. Check your AFV which will tell you if the ECM has been compensating for low fuel pressure.
