What do I need to change when rejetting my 2003 V Star 1100?

I have my carburetor out and attempting to rejet it. I moved from Charleston, SC (sea level) to Colorado Springs and the altitude here is 6,670 ft and I don't know what specifically I need to change or how much of a change I need to make in order to properly rejet my bike for the altitude. I need some serious help with this.
