Change interval for primary and transmission oil

I know there are multiple threads about when to change one's oil but I don't remember any threads about when to change the primary and gear oils. I just had the 5,000 mile servicing and put in Spectro primary and gear oils. Now I'm wondering when to change them out. Thanks.

I think that the best is to change primary oil when you change engine oil
 
It's only around one quart except for the newer bikes and gets pretty dirty from the clutch. I change it with the engine oil.
