yz woods bike

Feedback requested, I just got finished with some major upgrades to my stock 2000 yz 250. FMF gnarly pipe, FMF power core II exhaust, 9 oz steahly flywheel wt, 3.1 gal clarke tank. Switch from yamalube to golden spectra oil. The guys at FMF suggest changing the main jet from a 175 to a 170(got it but not installed yet, hopefully tonight, the rest of the carb, FMF suggests stock. Any idea what differences I should notice while riding it from the stock version. I havent had a chance to ride it yet, hopefully this weekend I can test it out. Thanks, the more feedback the better for comparison.
