Kx250 float bowl

Hey everyone I just perchased a 1999 kx250 and everything is really clean!...but after further examination the float bowl has a thick layer of an oil/sludge mixture covering the bowl and I know a few things about bikes but not about this im just curious as if this is normal and I can just clean it or is it a gasket or somthing hellpp pleasssee!! :)

I've never come across oil deposits in a carb. That would be a red flag for me. It's start at the top and works way down. Flush tank. Put in new premium gas and good quality 2 stroke oil at 32:1. Then pull carb. Since I've discovered ultra sonic machines. I do not clean carbs anymore. It's worth the little money to have it Ran thru the ultra sonic. It will get crud you could never get in your garage doing it yourself. Then pull plug look at piston dome. I'd even go as far to pull reed cage and inspect reeds, that way you can look at the intake side of the piston too.

Sorry what I ment to say was that its on the outside of the float bowl and I just dony know were to check for oil leaks or anything like that

And ive been trying to start it but now it wont hopefully its just due to the cold (my garage isnt heated)

Sounds like its just dirty. Is it oil, or dirt? My carb was REALLY dirty before I physically scrubbed the outside, and still didnt get all the dirt out of the cracks.

Its dirt and oil and im just tryingn ti figure out were it could be comeing fron

Either the fuel is leaking out of the bowl or it's chain lube getting flung onto the side of the crab.

      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.
