The second set of carbs will of been for an open exhaust. If you use the standard exhaust then run the 87.5/90. If not, use the 90/92.5.

That goes with a standard airbox setup also.

Did you take a look at the pilot jet sizes while you were there?

That explains it. Use the 90/92.5 and I take it the K&N is in the standard airbox housing? Not the silly cone filter type sat on top of the carbs?

You need to check pilots because you should be running 17.5's not the standards with that exhaust. Part number: Mikuni vm28/486/17.5.
