is there a chart for what jets you would need for dirferent altitudes like for a stock 04 raptor 660.i know my owners manual for my street bike has one for like sand mountain in nevada or like pismo beach thanks joe

The general rule is to drop one main size every 3k ft above sea level. But often times a jump of 1k-1500 ft will require adjustment of other jets.

Main jets example:
140/145 - sea level
135/140 - 3k ft
130/135 - 6k ft +
