push-in main jet question (on '75 cb550f)

bluayeddvl

ride it like you stole it
running stock keihin carbs on my 75 cb550f. i did a recent complete rebuild on all four and i made no adjustments on clips on the needles. but i did put inline fuel filters to keep things tidy inside.
just put on four foam uni-filters (lightly oiled of course) and will be putting on mac 4-4 header pipes to mate with the 4-2 pipes i got a little while ago.
currently have the standard #98 jets in and runs tops with fuel-air turned out 3/4 on each. but with the new headers i know i'll have to upjet, any suggestions on what i should work with without having to tear these fkrs out a dozen times to dial-in? 100, 105, 110, 115?
i'd guess at 105 or 110...but thats why i'm asking here, so i can learn from the pros.

using the list here (on right side of page) to get available sizes http://www.sudco.com/keityppre.html

thanks all.
