" will the O2 sensors on the UK-spec bikes be able to modify the mapping in the ECU to cope with the mixture changes"
Short answer NO.
The amount of "learning" in a closed loop system is merely to correct for production variation. When you pull the fly's you have made some major changes to the Volumetric efficiencies ( V.E. ) tables. V.E. tables are what "schedules" the fueling to the injectors in a Speed density system. ( Which is what the C14 system is as it does not have a Mass Airflow Sensor) If you pull the fly's you need a fueling device or you run the risk of running too lean at those part throttle point where the secondary butterflies were active!!!
