The JD kit is excellent for rejetting. It now contains the 42 pilot as well as the o-rings for the mod.
If you want to use Honda parts to get close, here is the set up:
Jet, Main (#152) 99101-357-1520
Needle Set, Jet 16204-MEN-671
Jet, Leak (#70) 99108-KRN-0700
Pilot (slow) Jet 99103-440-0420
Do the o-ring mod using the larger o-ring 3/16 thickness ID 1/4" OD 7/16".
