i'm at 3000 and ran 34mm keihin pj's with k&n pods, 175 pds compression, timing at +5 and used 38 pilots and 142 mains,air screws out 2 and a half turns and temp then was averaging 70 degrees.this may give you a starting point.i would probally go with 40 pilots and 145 mains air screws out 2 turns if i were you.keep check on your sparkplugs so that it is'nt burning to lean.hope this helps ya.
