Ivans needles

I have an Ivans needle set with A and B needles. Does anyone know which needles i use for a standard RD500?
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 , cheersRichardUK500 wrote:I have an Ivans needle set with A and B needles.
