You are running lean after all those mods. One of our members, Randall, was able to add a rheostat to his wiring to vary the fual/air mixture in his Yamaha. It was not a Delphi system, but it had a mass airflow (MAF) sensor.
He isolated the wire to the mass airflow sensor, and added the rheostat to it.
