newer wrf needles on older wrf 250

Has anyone tried to run the stock '07 WR 250f needle(NJRU) on '04,05,or 06 250 wrf? Stock needle on the '05 is OBERP. Also, Can anyone direct me to where I can find a chart revealing comparative data about all the needles for the 250 yzF and the 250 wrf? Thanks for the help.
