If I had a dsl driveway OR highway, I'd go check myself....;)..but to verify, the 150 isn't a typo?? I don't think that's right (even if I
DO have a >'95 200!!!
CDave says: (I realize he isn't necessarily
stating the stock jets, but what should be run stock. That isn't likely to be richer than stock, though, which it would be if he says run 155 and stock is 150)
1989 to 1994 KDX200
Stock -Run the stock R1172N jet needle in the second from the top clip position, 48 pilot jet, 155 main jet and fine-tune the pilot circuit using the air screw.
With a performance pipe/expansion chamber, the air box lid removed and the stock or a performance silencer run a 45/48 pilot, R1173N jet needle in the mid clip position, a 152/155 main jet fine tune the pilot circuit using the air screw.
Addition of Boyesen reeds or a Boyesen RAD Valve will require you to lean the pilot and main jet one size and readjust your air screw.
