I'm looking for some elevation info. I'm getting ready to head out to Colorado next week and am wondering if I need to change jets or not? I bought the power-up kit, but hav'nt installed it yet because I'm still happy with the stock set-up for now. The elevation here is about 630 ft.asl and I'll be up to 14,300 ft.asl. I know that there is going to be a difference in the way it runs, but will it be enough to require a change? Ive always taken 2stroks but this is the first time for a thumper. If there is anyone out there who may be able to give some input, I'd really appreciate it. Thanks.
