YZ400F Jetting

[CRboy167]

I just bought a 98 YZ400F and the person I bought the bike from changed the jetting and I want to put it back to stock and then try to adjust it from there. Its running lean now. I live in the Chicago area and that not that far above sea level. So if anyone has the jetting lined out that would be a great help. Thanks for any help

Check the FMF website. They used to have all kinds of jetting info there (including stock).
