s8 or 9 nozzle?

Hi, I posted this up in jetting section but thought this may be a better place to ask, its an 03 cr250, and I cant remember which nozzle is stock,s8 s9? thanks.

S9 is stock the S8 (1 size leaner) will lean the overall jetting. This is one of the first mods I did to the mikuni & it helped a lot before I got a jd kit w/s4 nozzle. The JD needles are configured to work with the s4 nozzle for the 02-04 CR250's.
