so i have read that keeping the stock carb setting is not good. so I'm asking all of u in your infant wisdom what would be the best jet kit both performance and bang for your buck? i have a 04 raptor with no mods besides a modified air box and a k&n filter. my friends think that the carb is already jetted but i just don't know so i would like to start a new. my riding elevation ranges from 5500-8500 feet. is that to much of a gap to find a happy medium? please tell me everything I'm new to this and very eager to learn.
