Question about jets

[Bigsean]

Hey all. This might seem stupid but here's my question. I have a 98 kdx200. Also a yz125 and a xr 400. So I have lots of jets for the Keihin carb. My yz has a Keihin. Came stock with a mikuni but anyway.my xr has a mikuni pumper but the stock carb is also a Keihin. So I have lots of keihin jets.just got the kdx and it has a 160 and 48 set up. Seems rich. Can I use the other jets I have. They look the same but was wondering if the jets for all the Keihin carbs can be swapped around.
