Here is the final update:
RPM's for CDI converted Rotax 185 engines.
Left Engine 5770 rpm
Right Engine 5860 rpm
I noticed the Left was a little slower so I advanced the ignition slightly but there was no significant difference.
Since its only 90rpm, I'm not going to bother equalizing them for now.
These are new engines with only 4 hrs TT on them so perhaps they are not quite broken in yet.
CDI conversion is complete and working beautifully......1 pull restarts every time....so I can shut them down in flight to thermal, with confidence of getting an easy restart.
