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.

Dave
