Does anyone have any feedback on Ivan's needle jets/emulsion tubes?

I need a set for derestricting a RZV and the OEM RZ500 parts are proving pretty difficult to track down.

years ago when i purchased my needle kit , ivan recommended the '' B '' set for slightly modified engine aftermarket pipes intake filters on the carb flanges and such the B profile was the smoothest transition throughout most of the rev range with needle clip middle slot .... '' A '' needles for a stock setup was what ivan told me in 2007 , every motor is a little different , cheers
