If the bike is running right on boost but is rich at low revs it sounds like your pressurising the carburettors OK. I'd try doping the needles, then setting the pilot air screws for best fast idle. I don't know how you have designed your system, but if you haven't got a big priority air valve then when the bike is off boost and in effect naturally aspirated you will have a much greater restriction to the air flow than a bike with a stock induction system. I assume the bike is maybe having to suck a lot harder at low revs (off boost) and this is causing it to run rich.
