Colorado Jetting

Recommended Posts

Hey guys,

 

I am thinking about buying a FMF Q4 pipe for my 2006 XR650L, I typically ride around 6000- 9000 ft

Any suggestions on jetting? I was thinking about doing Dave's mod as well

Any input would be appreciated

A 152 or a 155 main jet, depending on how open the airbox is.

The jetting on my bike (158) works well from sea level to 6000 feet, and it's on the rich side, even at sea level.  Some people seem to believe that you need to adjust the jetting every time you go up and down 500 feet.  It's not nearly that sensitive.
