look in your manual it tells you what the stock needle number is.

The stock '07 needle is an NFLR. The 4th letter indicates the base diameter of the upper end of the needle, above the taper. That diameter is used to adjust the mixture from off idle to about 1/4 throttle. This works in reverse from a jet size, as the lower the letter, the smaller the diameter, the richer it is, because it takes up less space in the needle jet.

See page 7-7 of your manual.
