Oil change Dry V Wet clutch interval ?

[Two dogs]

With my wet clutch bike I change my oil and filter at around 2.5 thousand kilometers .
Now with my dry clutch motorcycle  I am not getting particles from the clutch plate
distributed through the oil bath theoretically increasing the life of said oil.
If so what oil change interval for the dry clutch motor same or longer oil life?
What say you ?

I've always used 2.5K miles for my dry clutch 900.

I also like the idea of changing at the end of the riding season if you don't ride year 'round.
