[QUOTE="mattb348, post: 990756, member: 62675"] I have a 2002 KX 500, which seems to be jetted pretty much perfectly. The only mod it has on it is the PC pipe & PC factory sound silencer, which it came with when I bought it. I suspect that it still has the stock jets in it, but I haven't checked yet. I tested it at all different throttle openings, and it seems to run perfect; no crackling or bogging or anything, none of the red flags. I still have to do a WOT plug chop though. My question is this: do the 2002 KX 500's come with a rich pilot jet like the 250? Becuase the 250 pilot jet is like 4 sizes to rich! I suspect it may be to rich because the pipe has alot of oil all over it, way more than my 250 ever did. It hasn't fouled a plug yet while warming up, which is something my 250 did like every 3 times you cold-started it, but I really haven't started it enough times to be able to tell if it is going to cold foul a plug yet. Thanks for any info guys! [/QUOTE]
