[QUOTE="lemmy, post: 1314807, member: 93740"] I have a 2003 KDX220 with the 35mm 200 carb. I have a new spark plug (BR8ES), 44:1 new 93 octane gas (Motul 8002T), CEK needle with clip in #3, 35mm pilot, 155 main, 1.75 turn air screw, woods pipe, newly packed powercore2 silencer, RAD valve (reeds in great shape) and float is 17.5mm and clean air filter. I can start the bike easily when cold and immediately turn off the choke (might even start without it) and it idles fine. Even after riding for 5-10 minutes it idles fine. But after 30 minutes or so it won't idle or will idle just barely even with the idle screw all the way in and no matter what I do with the air screw. If I pull the choke out it is even worse (so I assume it isn't too rich). Any ideas to try? I recently fixed the kips (it was stuck open due to previous own putting the "claw" on incorrectly) and now it opens when it should and closes (slowly). It doesn't seem to return to the fully closed position at idle but it is within 1 tooth on the gear under the slotted cover. I manually turn it all all the way closed and it doesn't make a difference. [/QUOTE]
