    not many vacuum lines... and logic tells me it's unlikely a vacuum leak, more likely a plugged vacuum line... maybe a passage inside the carb

    doesn't have to be a vacume line cracked intake boot, loose clamp, cracked o-ring in air/fuel screw, bad seal in the carb tool itself... there are tons of places air can leak in

    It would read LOWER if you had a vacuum leak.....
    Higher means throttle plate/slide is closed more than the others

    It's a fun ride.

    I hate it with the lower fairing, looks like a new dress on the old whore and it's heavier and slower with it. Go figure.
