[QUOTE="ichiSan, post: 210228, member: 4493"] thnx... im going to paste these instructions here.. the pipe and air box mod (3x3 basically putting a huge hole in it so it sucks way more air) seem to definitely require the re-jetting.. i got a guy taht's going to do the work for me, im on the west coast and i just got here got no tools! :( anyways i gotta bring this guy exact instructions cuase he has no dyno.. ------------- Here's what i found ---------- Since I've been getting a few requests a week to e-mail the re-jet instructions word document (offered to send it to someone in old post that lives on) I thought I'd throw this post together. It is perhaps the one stop shop for 3x3 mod info: the master 3x3 post The 3x3 Mod Sample Jetting recommendations (note: these are different for different elevations and different bikes) SM - 150 main jet (155mj for full exhaust system - 25 pilot jet - 2nd clip on needle from top - 2.5 turns out on fuel screw S - 140 – 142.mj (bigger for exhaust) - 25 pilot jet - 4th position from top - 2.5 to 3 turns out on fuel screw Burned’s fuel screw setting method: with the bike warm and idleing turn the fuel screw in till the idle drops/misses.then go back out till the idle peaks/smooths. this should happen between 1 and 3 turns out. if you end up at less than 1 turn you need a smaller pilot jet.more than 2.5 (or 3 turns on a cv) you need a bigger pilot jet. choose the appropriate size and retest.
