Doesn't sound like oil pressure, sounds like crankcase pressure ( blowby).

Near the top of the motor is a large tube about 1/2 inch diameter.  This is the engine breather tube.  Make sure that tube and whatever it is connected to is clear and free flowing.  Flush out any barnyard animals hiding in there.  The oil tank has it's own breather tube, too.  But, I don't know that system well enough to explain it.  I'm more familiar with the Cb550s.

Cheers,
