KAWASAKI TECH TIP #14: 2001 JETTING SPECS

We get pummeled with e-mails everyday wanting to know the perfect jetting for their 2001 KX. The truth is we know the perfect jetting for KX’s at sea level running standard 92 Octane pump gas at Sea level altitude. So if you use race gas or don’t live anywhere near sea level, use these as base line numbers and go from there. If you are lucky enough to live at sea level, enjoy the clean jetting.
