I've never seen a Zeeltronic fitted to an MC16, so will be interested to hear about your results in due course.
Here are the ignition specs from the MC16 section of our Honda approved NSR250R Service Manual:
I would suggest initially opening the RC Valve at around 7000rpm, and experimenting from there. Even the MC16 is a bit more sophisticated than simply opening and closing them based on RPM, but there is little data available.
