1987 KDX 200 Jetting

[ZKDX]

Anyone tell me what jetting works good for this bike...that is probably pretty vague, but i've never rejetted anything. i'm running stock exhaust (for now), 90% woods riding, and running stock jet now (or at least i believe it to be)....How do you know what size the jet is, i've taken it out, but see no stamping, do you just pin gauge the i.d. of the jet?

The numbers should be stamped on the jets. Look careful, they are very small

standard was a 320 main, can't remember the pilot. Drop the main to a 310 and experiment with the needle clip positions. You shouldn't need to change the pilot.
