Ill do you one better. You can order the jets you need on this page. http://jetsrus.com/a_jet_kit_dirt/ho..._1992-2009.htm
Ill also give the best advice I can give you after owning a xr650l for almost 5 years. After the Dave's mod. Setting up the suspension correctly will really make the bike a lot more enjoyable and safer on the road and trails.
