That super trick 'priller would be Andy Graham.
An Idea for you. Put race pipes and 36mm keihin carbs off earlier RS125GP bikes on. I've got 38mm ones on my Aprilia, and I'm going to buy 36's.
I had a look at the angle that the carbs go in at on the NSR, and with the right hand carb rubber off an RGV250 the angle is about right. You would need a block of probably 12 or 16mm aluminium or petrol resistant plastic to bolt onto the NSR intake, that you could bolt the RGV rubber to. One side would have to be milled to angle the carb outward.
You would also have to cut the rubber lugs that stick into the reed block off the carb rubber.
Untill you've tried it, you wouldn't believe the difference in power
