It would be interesting to stick a multimeter on the pump next time a bike with oil injection is on the dyno, and do one of your famous "ride-out" runs Steve. I have a feeling that it's not "cold enrichment", but possibly something connected with RPM for slow speed and load.
I don't think there would be any adverse problems with running a pump with an HRC harness, but would prefer to know exactly when the pump was getting a signal from the PGM to try and understand exactly what it's supposed to be doing.
