Free is a word I like :) Have you ran the new top end in good? A good 30 min casual ride should do it, don't rip it just ride. If you think your jetted rich take you carb off, remove the bowl and there on the bottom of the carb you will find 2 jets the center being your main and the one off to the side will be your slow jet. Their will be numbers on the jets, mine are 158 main and a 45 slow, going smaller with the numbers will lean the system but go in one size diferent increments at a time. Changing your needle jet will also change the system, choosing a diferent clip setting on your needle, move the clip twords the top and it will lean it. Best bet is to do a jet search on here, their are many links.
