Kevin,
I highly recommend NOT operating the engine without a load. I wouldn't begin to even THINK about changing things without operating it under load. BUT.. oil pressure can be adjusted by dropping the pan, taking the REAR oil pressure regulator and either putting a stiffer spring in it, or putting metal blanks/shims/coins inside the barrel to compress the spring. But keep in mind, even at 4000 rpm, you are generating very little power due to very little load. If you blip the throttle too much you could easily exceed rpm limits. be careful.
I'd cover the oil fill with a shop rag.. something that breathes but keeps stuff from falling in the sump.

I am running my new turrentine-built 2004 renesis engine without a prop right now, so no load. I noticed about 60 lbs oil pressure when first started, cold. I made a few runs up to 4000rpm after some warm up and noticed oil pressure reading more like 40 lbs. this seems bad. can I adjust oil pressure? what else should I be looking for?
also, what should I put over the oil fill tube? it is open, with 2 thin bolts protruding.
