05 CRF450X - jetting for mixed altitudes

Recommended Posts

I am about ready to install the JD jet kit for my bike, but had a question about which main jet to use. I live at about 2,700 ft and do most of my riding between 2,500 ft and 4,000 ft. The jetting instructions recommend different jets and needle settings for 0-3,000 ft and 3,000-6,000 ft. Since I am right at the borderline between the two settings, would it be better to use the low altitude or mid altitude jet setting? Which setting would give me the best performance for my conditions without having to constantly re-jet everytime I ride above/below the 3,000 ft mark?

Thanks.

Eddie, can you shed some light on this? I'm curious as well.
