I have a 96 KDX 200 W/ 240LA sleeve big bore, FMF K-30 pipe and silencer, Yamalube 40:1, 45p, 158main, stock needle w/ clip on top, (full lean), A/S @ 1 1/2, airbox lid removed, 12tx52t drive, fresh top end. I weigh 165 and ride tight rocky mountain single track.
The bike came w/ these mods and has loads of power and snap. I want more low end torque as I spend much time shifting between 1st, 2nd and 3rd on tough rocky climbs w/ plenty of mud. I'll gladly give up top end as I hardly need more than 1/4 throttle (front wheel is up already). I want to be able to idle along in 2nd or 3rd better without having to drop a gear when thing get tougher.
Question 1. Will the k-35 pipe help a lot or just a little? Anyone out there want to trade?
Question 2. Does a 45p jet sound rich if I'm getting some smoke and some spooge (note, I hardly ever get into the main)? Can leaning things out produce better performance down low? If I understand correctly, these things can run well w/ very little smoke.
