08 ktm 530excr HELP !!!!

well i put my stock header back on after crumpling the akro i had on my bike and now i have a overly blue head pipe. im a jetting noob but i know that a blued headpipe can mean bad things. i have the jd jet kit installed on it with an HMF muffler (no SA or quiet core) and i ride just below 1000ft and i need to know if the recommendation hmf gave me for a 215 main jet is too much ?
