stock '06 yz450 needle

Can you guy tell me what the stock needle code for the '06 yz450? Looked in the fiche, but they show a lot of difference needle. Also, which main and pilot


Hey, Fasz Kalap!

If I'm readin' my manual correctly, an NFPR is the stock needle (clip position #4), the stock main is a #165, and the pilot jet is a #42. Fuel screw out 2 & 1/8 turns. Hope this is correct, and hope it helps!


Thanks !
