[Ducati] 748 oil pressure

[PJDemoga at aol.com]

Hi Listers:
Do I have a problem because my oil pressure warning light comes on at  idle?
It's only after the engine is hot, but it never used to do it.
I had a recent oil change, no leaks, and the level is fine.
The only thing I can think of that might make a difference is the fancy new  
crankcase breather.
Am I worried about something for nothing?
I'd rather be looking for the apex than the oil light>
