Thanks embee. I unplugged the output wires on the new reg rec and the reading dropped to 0.1mA so it looks like that's the reason for the change. It's definitely the reg rec itself that's leading to the slightly higher reading, not the bikes wiring.
As you say, accuracy of the meter is probably relevant - my multimeter goes to 1 decimal point in that range so the actual difference could be really tiny.
I'll do the load tests on the stator and reg rec output next time I get a chance and see how that goes.

Run-of-the-mill DIY item so it sounds like close is good enough.
