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
