Motoman's jetting predictions

Jet settings on the motoman website (162mj, 4th clip, 42 pj) are way leaner when compared to what JD suggested to me (170mj, 5th clip, 48 pilot). Why is that?

After all , my bike is almost like a YZ426 now (timing, FMF PC4...)

I'm getting confused.

(0-2000', riding temps from 40-85).

426 and earlier had different MAJ's and no ACV circuit so they will jet differently than our 450's. :)

I own a 426, not a 450...
