[QUOTE="KylePeterson, post: 1445319, member: 128923"] agreed, it's fouled two br8eix iridium plugs (or three, i don't remember). i switched to the br8es (non iridium) plugs, and got two full days of single track out of it without issue. i did a couple of plug chops with new plugs after the ride, while the bike was still HOT to get a decent read of the plug. the attached picture is a 3rd or 4th gear WOT chop, running Lucas oil 32:1, 38/136, middle on the needle, and 2 1/4 turns out on the mixture screw. it pops a little on deceleration (down hills) and pulls strong from the basement to the sky. but, that nasty off-idle sputter is still there at steady throttle going down the road. the colors of the plug are misleading in the picture, so i'll clarify what they really are: plug threads and face = biscuit tan / brown to oily spooge plug insulator = gray to black deeper in bent electrode = gray to black electrode = black **** last week i rode a rmx250, and expected a similar sputtering when held at constant speed on the road (connecting trails). it was smooth as silk running at 35-50mph in whatever the top gear is. really made me want to make my kdx run better, as that bike is much more managable at cruising speeds. i know the kdx is a woods bike, and a love it in the woods, but if this isn't possible, i may need to starting looking for an old rmx250 to pick up and resurrect. the wide ratio transmission was really nice, and it pulls so mildly from the bottom, with an even more linear power curve than the kdx.... i liked it. a lot.
