Hi, if you click back to the home page. On the upper right side is a "how to" section, Click on the fuel line and it will lead you to a jetting chart. Or if you click on the kx500 maintenance and technical area, and look at the upper part of the page, there is a topic entitled" jetting again and again"  ( I think there are nineteen pages )
  Those are the two areas that I go to for jetting help.  Hope this helps and that you get that bad boy jetted right.   John

Johnniespeed:
 I  forgot to tell you, that there is a search function at the top of the page and you could type in "jetting"
 And I also forgot to tell you that adding a FMF gnarly pipe to my bike , it ran a little rich. I needed to lean it out a little.   Hope this helps.  John
