I am trying to follow this indy450 jetting chart and it says for 60 to 75 degrees @ 0 to 4000 ft use a 165 main, jd red #5 or jd blue #3 , 48 pilot, 1.5 turns, 70 starter jet, #40 leak jet. I dont know what is stock if you could let me know that would be great. Also would like some input on which I should change. If anyone could give me the advice on taking out the baffles on my exaust that would be great. Thank you for your input.
