I have 2002 CRF 450 and the JD jetting kit, also installed hot cam and FMF power bomb pipe and muffler. I'm headed to Taylor park Colo and riding at 10,000ft and above. Just need feed back on which way to tune the carb for best performance or any suggestions for what works best.

JD has allot of info in this.

My experience is to set it to the highest altitude listed in his his instructions and forget about it. The 450's are very forgiving.
