The stock c-clip position on the tapered needle is in the 5th position which is all of the way raised. (As rich as it will go). So putting on a Turbo pipe, doing the airfilter mod would make more air so it would seem that you would not even bother changing the c-clip...because any other position would be leaner. Correct thinking? I changed to a 60 jet and it is chocolate brown at full throttle.
I know I can do a plug chop at 1/2 throttle to see but the thinking would be.. if the richest needle setting is good for stock.. you wouldnt change it with more air flow. Right? (edited)
