my 06 kdx200 has about 16 miles on it went to start it and it fowled the plug i shook it pretty good i thought to mix up the fuel/oil does the fuel/oil separate and the oil go to the bottom????

Yes it does separate. Some oils more than other (petroleum Based-More So, than Synthetic) Always should shake before starting. Don't let the bike idle too long, especially when cold, you will foul for sure.

What oil and ratio are you running? If you're running cheap stuff, you're asking for a lot of trouble with the KIPS getting caked with crud and other problems. It sounds likely that since your bike is so new, it's not jetted right and that's why you're fouling plugs. At idle/low throttle it's mostly your pilot jet, but the main comes into play a little. Read the stickies on jetting and do that. Don't start messing with the spark plug heat ranges to mask jetting problems.

My bike can run at idle for quite a long time without fouling.

I can say..... I have never fouled a plug in a KDX.

My jetting has always been pretty close... even when buying one from someone. I always look at the jetting before riding a bike for the first time anyway.

Dont go messing with jets just yet!!!!!! first off your bike is new it isnt even broken in until around 65 miles as per say your manual says my inital plug ( i have an 06) was changed out after the breakin period. use the sugested 32:1 ratio that it comes jetted for as well making sure to use a good oil. maxima super m etc. ( diferences vary here but i dont have a problem and never have on any of my bikes). And yes, as told the oil will seperate, as well as the fuel will lose octane after sitting for any lenght of time. my advice pick a nice day, use a new plug, and fresh fuel mixture. go break the bike in properly Again about 65 miles! (took me two full days of riding to achive this). never go full out or lug it around during this period shift as often as possible once done change the oil and perhaps the plug once more and you'll be set.
one variable to this is that the bike comes jetted for 0 1500 ft and a little on the rich side. depending on your general elevation and outside tempature your jetting may need to be adjusted ( mine didnt) but not till after break in richer is definitley better during breakin and when it comes down to it i'd rather run a little rich and be protected then to lean and risk failure of the engine. and I have never fouled one either was close to during breakin in though plug was getting pretty bad when i changed it out after break in. now plug comes out looking normal dark tan with no sign of fouling.

ps if you hit some wet grassy area you'll find out real quick you need to change that stock rear tire if not both

i am running 32:1 mix with yammalube oil i am not sher the eluviation i live in the base of the great smoky mountains i east tn. it was about 38 deg. when i ran it for just a little wile after i changed the plug it ran fine it was just a little confusing a friend of mine has a yz250 and fouls plugs often when he shuts down a have herd to shut off the fuel and twist the throttle 2-3 times and let it come back to idle then hit the kill switch does that sound wright ?

The last plug I fouled was in the summer of 1973 on my Honda SL125 (4 stroke).

Jetting makes all the difference. Face it....it's rich.

Go to google, type in the town in live in (or the closest big town) and type elevation after the town name and that should tell your elevation. Jet from there.

thanks mark i found out my elevation is 945 feet here in walland tn. i will try to run it a little this week end it is hard for me to run for more than about 2-3 hrs at a time i have a 3yr old boy that i love to spend as much time with as i can it will probably take me acouple of weeks to get 65 miles on it

also is there any fix for front end wabble when running on the road (i have to to get to were we ride here by the house)?

by wabble, do you mean the head-shake type oscillation at 70 mph that feels like if you hit anything it'll throw you into a massive life threatening tank-slapper ? I only had that happen on loose gravel roads, and enjoyed it so much I put a Scotts steering damper on it. That took all the exitement out of that. Expensive though.

You might want to make sure your steering head bearings are lubricated, in good shape and tightened to spec. Also, that your forks are aligned and the rear wheel is tracking straight. Both wheels need to be true too, and balanced if you ride fast.

Putting a dirt bike on the street is tough though.

it is a new 06 i mean at about 40 it gets squarely the dealer i got it from said i did not need to grease it until the scheduled maintince should i check that or take it back to the dealer

hey first chance you get Tear into the sucker and grease it!!! my 06 didnt have barely a film of grease on any of the bearings the rear linkage was almost dry!!!!

where are your forks positioned in the clamps? is the cap on the top of the forks just about level with the clamp? if its more then a quarter inch up you start losing straight line stability, on the other hand the higher it is the better it corners. I have mine with the fork cap just barely above the top clamp. I did notice the front end wanting to slide out once in this slippery section of hard pack that is straight, but i attribute that to the junk stock 739's which will be replaced soon wil 756's or a set of the maxis tires my friend has, I'm waiting to see how they hold up as he's getting awesome traction

ps do your own maintenece and keep reciept beats 60.00 hr and a log that way they cant argue you didnt maintain it. didnt have to use my warantee after the first issue with a float problem the day i brought it home they ended up changing the whole carb after checking the ffloat height and seat and finding they couldnt get a replacement seat.

thanks i will tear into it and check iti out

let us know the outcome of your search for grease bet you dont find much

I just repacked the steering head, swingarm and linkage bearings on my KLR650. I don't think KHI owns a grease gun.

As bad as it was, at least the rear axle was fairly well greased.

I just had to remove the rear wheel on my (new to me) 98 KDX220 to install the Devol disc guard and it was heavily rusted. Based on this I'm not looking forward to seeing the state of it's swingarm/linkage. Bike doesn't have many hours on it but I'm guessing it's never been relubed. I'm hoping I don't have to do anything more than squeeze the trigger.
