I have an 05 KDX220. I replaced the stock exhaust with the fmf desert and II silencer. I replaced the reeds with the Boysen power reeds. I finally replaced the stock carb with a 96 KDX200 carb. My problem is after reading many of the threads on here it seems that you are jetting your 200 carbs much richer than I can get away with. The first thing I noticed was I had to jet the 200 carb leaner than the stock 220 carb to get the bike to idle and run crisply.
KDX200 carb in a 220
idle jet = 38 (any thing bigger and you have to turn the idle screw in 90% just to get a sloppy idle.)
Float is adjusted
main = 142
Needle = R1173K #2 clip
Air screw out = 1 3/4 to 2 turns
Premix 40:1 synthetic
Altitude at which the bike is ridden 1317 feet to 6000 feet. Mostly 3000 to 4000 feet.
My friend who owned KDXs with very modded motors says I am running scary lean. Plug chop shows a creamy light brown or rust color. Seat of the pants says it is awsome.
Anyways my friend scared me so I rejetted to a 148 main with 2 turns out. Idle isn't quite as nice but still acceptable but now the bike loads up really easy if your not into the throttle.
Have any of you safely jetted it as lean as I have and been OK?
