Rejetting '03 KDX 220

[Hawk5443]

I just bought a 2003 KDX 220 and have not even taken delivery yet as it is being shipped from RI, which is about 180 ft above sea level. Where I live is approximately 1400' and I will ride in areas 700' to 1500'. What jetting should I be looking at for this elevation change.

Thanks,
