KDX Trouble

I have an 06 KDX 200 and can't get it to start. Its got fresh gas, clean carb, , good spark and the reeds are fine. it has stock jetting and a FMF Gnarly pipe. It's currently around 30 degrees where i live, thought the temp. might have some thing to do with it. can anyone help?

Get me a plane ticket and I'll come kick it for you?

You need three things. Spark, fuel, and compression. One of these is missing. I can't tell from here which one it is.

Maybe try turning the petcok to off, crack the drain on the bottom of the carb and let it empty. With the drain cracked open turn the fuel back on and make sure it is flowing.

You pop out the plug and drop some gas in there yet? Wonder if that would help... maybe it just needs a little priming due to the temps.

Turn the fuel petcock on, lean the bike over till its just about touching the ground until fuel runs out of the carb overflow, bring the bike back up and kick it. It should start within a few kicks. In cold weather I have to do that with my kdx220, it works every time.

Yeah, your missing one of the big 3. Your SURE it's getting a good spark? Sometimes it will spark with the plug out of the cylinder, but won't actually be enough to light the mixture under compression.

Something's not there. Temperature won't make any difference unless it's like, 10 below zero. 30 degrees, it should fire right up.

Turn the fuel petcock on, lean the bike over till its just about touching the ground until fuel runs out of the carb overflow, bring the bike back up and kick it. It should start within a few kicks. In cold weather I have to do that with my kdx220, it works every time.


Except turn the petcock off before laying on its side. Than turn it back on...Check your plug also

Pull the airfilter and shoot a squirt of starting fluid into the intake then kick it; if it won't start then you have Issues.

I've had plugs that looked like a good spark but wont fire the engine. Replaced with a new and the bike would fire.

Pull the plug and let the bike sit for 30 min to dry the cylinder and try a new plug. Start kicking without gas or choke on, after a few kicks gas on/choke only, few more kicks then a few twists. If it doesn't start pull the plug and check for excessive wetness, your bottom end might have flooded with a stuck float or leaving the gas on.

I have dried a plug with a plumbers torch and one my wife didn't like...lay the threads on the range element and turn on high. It'll smoke like crazy and after awhile a flame will poof out of the plug, wire brush and she's ready.

      Alright so I just rebuilt my 2012 kx250f complete rebuild. I put the motor back in the bike get everything hooked up and ready to go it takes a few kicks at first (obviously) but after it starts it sat and idled just fine for a while then it stalled out. Tried to start it again wouldn't start I took the spark plug out of it it looked good I was dark and wet. I cleaned it then put the spark plug back in it it took a few kicks but started right back up again then after a while it stalled out again and now I can't get it to start again!? Any help would be greatly appreciated thank you guys and girls for reading and hopefully for the help!!!

      Hi all,
      I have a 2004 Kawasaki kx250 that died suddenly on me the other day. all i can get it to do is backfire every once in awhile. Tested the resistance and everything of the magneto and stator with a multi-meter and all is good.  Coil is new oem Kawasaki the reeds are brand new vforce and the top end and carb have been completely rebuilt.  key on crank is intact and all the timing marks are lined up. I hooked a timing light to it and spun the motor over really fast and found that it is sparking way to late.  The service manual says that it is supposed to fire 14 degrees before TDC but it is sparking way after TDC.  Im thinking its a fried CDI box since its the only thing i wasnt able to check.  Any help would be appreciated

      Hi all,
      I have a 2004 kx 250 2 stroke and it wont start.  it only backfires.  I was out riding it one day and came up to a stop so the bike was just idling and it started to try and die so i revved it up a few times then let it die and now it wont start back up.  It only pops or backfires when you kick it.  Its getting good spark and i just put a brand new plug and coil in it. I took the reeds apart and they look like they're brand new.  It was running great before so i dont know what happened.  Im thinking it could be a fuel problem even tho the plug is a little wet if you take it out after a bunch of kicking.  Any help would be greatly appreciated

      Alright, found three bikes all located where i live in Texas. I know they're all very different, but if you could tell me what you think each bike is worth, and which one would be the best deal. Thanks.
      Notes: Both 2 strokes have new top ends. I think the front brake lever is broken on the kawasaki.
      KX250 2002 $800-$1000?

      YZ125 2000 $1250

      KTM 400SX 2002 $1200

      So I'm at a bit of a cross roads, I currently own a 06 rm250 and I love it. I also have a 02 kx250 which I'm selling with intent to buy a newer two stroke. I can't afford a newer ktm and the older ones aren't that great and kawasaki never impressed me. so I'm stuck between 06 yz250 and 05 cr250. I've heard the yz and rm after 06 are almost the same bike just the Suzuki handles better and the Yamaha has better suspension. So I'm not sure if I wanna buy carbon copy of my bike with slight differences. That's why I'm interested in a cr250 I heard the 02+ models RC valves are shit garbage but was mostly fixed in the 05-07 models. I ride at a track and at some bogs down the road from me. So from people who have owned both, what would you recommend. I know the cr is known for a hard hitting power band which I enjoy since im an aggressive rider. Should i just see which deal comes my way first.
