just wondering i'm going riding around st. joseph (elevation 1000-3000ft.) this weekend and i'm getting some mods, but the thing is i'm not gonna have time to fiddle with the jetting. So i was wondering about what size main jet would i need? and would i need to move the needle clip any?

Here's my setup (already listed, but just in case)
2004 KFX
stock engine
airbox with K&N and removed lid
slip on titanium 4 with mid pipe

thanks for any replies.

If your talking about St. Joe state park MO, then the elevation is below 1000ft. I live about 80 miles away and my elevation is 472ft. above sea level..... I know St. Joe is higher, but I don't think it's anywhere near 3000ft.
