hows it going guy, just joined the forum after lurking for a few weeks. just traded a 2012 cbr 1k for a 09 sm yesterday (i know call me crazy) i guess the bikes previous owner faulted on the loan and the dealer took it back. its got a few mods done to it but i have a question about one in particular. my bike has a yoshi rs-4 (dual pipes) with 3x3 mod. now i plan on ditching this exhaust this winter when i start getting into some engine work/carb upgrade. right now it runs pretty friggin lean, pops like crazy on decel and sometimes in between shifts, even starts cold without choke lol, sooooo my question is i want to tune the bike close to a good a/f ratio while i ride for the next few months so i was wondering if i can do this without buying the 80 dollar jd jet kit as i plan on getting rid of this carb this winter and i feel this will be a waste of money.
