Ok, it like this. 2006 drz s brought new, put a dyno stage 1 kit on it with a k and n filter on it and a full dep exhaust. 134 main jet needle on 4th clip. Very pleased with it. My dad's got a STOCK dr 350 so naturally it was faster. Both of us run with a 14t front and a 47t rear sprocket. Now i've done the 3x3 mod, thats a 142 main and 25 pilot, needle still on the 4th clip and screw at 2.75, i've even put a full yosh rs2 on it as well. Went out with my dad today and he was all over me like white on rice, the straights i couldn't get near him. Not at all. So clearly some things wrong, maybe need to move the clip, i'm not sure. All i know is that the bike is now slower than stock but worse than that it's slower than a 10 year old stock dr 350. Any ideas would be a great help, as i really and i mean really, don't like my dad laughing at me.
