[QUOTE="Kawi4life, post: 893262, member: 59272"] Well I just couldn't wait till tomorrow to atleast put one of the new jets in so all I'd have to do is take it out and ride it tomorrow. Only took ten minutes to put the needle back to stock and change the pilot (didn't even have to take the carb off, just loosen and tilt it). I decided to put the needle back to stock and just make the jump over the 50 pilot to the 48 because the way I see it, I was getting smoke on the very bottom and the mid to top was feeling spot on with no smoke. After I was done it was still plenty daylight out to roost up and down the trail to try out the new jetting. I was a little worried that I might be going too lean jumping straight to the 48 (especially leaving the needle in the leanest position) and get those little "blips" when you punch the throttle from low rpm where it feels like the fuel cuts out for a split second but to my suprise it didn't and it has nearly cleared up all the smoke. After ripping on it then comming to a stop, it takes nearly a minute to get even a little smoke out of the exaust, but it's barely noticable so I think I have the jetting fairly close now. I "might" even try one more step leaner on the pilot for sh[i]i[/i]ts and giggles since it's an inexpensive part and easy to swap out. But it's so close now, mabye another half a turn out on the air screw will make it "perfect". Just for reference incase anyone else out there has a 2004 KX250 and needs to cleanup the smoke/exhaust spooge on low end, I've changed the stock pilot jet of 52 to 48 and went 1/2 turn out more over stock on the air screw and left everything else factory. It's nearly perfect now, I might not mess with it anymore. A little "hint" of smoke that's barely even noticable after idling for a minute might not be worth messing with. [/QUOTE]
