I'm swapping out a single Empi carb for a stock rack of carbs, bike is an 85 and the carbs are 86. Listed in my manual is main jet size 108. My rebuild kits came with 102. Installed in the carbs were 105. I also have spare dynojet jets starting at 108, which according to the jetsrus chart equate to a Keihin 112. So, which do I go with? The 102 are two sizes leaner than 108, the 105 is one size leaner, the dj108 is two sizes richer. Right now the bike is going back to dead stock, but I do have a set of jardines that may go on if I can clean them up enough and decide not to sell.
