2005 crf250r jetting

Hey i got a jd jet kit for my bike and it has a fmf powercore 4, its ported polished, and has a k&n air filter and i was wondering if i should stick with what the kit says or if i have to change needle clip settings or what? i have never done this before.

o and i forgot i ride from 0-4000 feet

install it exactly per the instructions.
