Major problem..fuel running out of carb..kx-125

Well this problem has came and gone, but now it constantly drains gas out as fast as possible. It is coming out of the bottom of the carb in the back, the line that comes out there. I also have a problem with the bike bogging in first gear. What would be causing this? Could the problems be related? Thanks alot for the help.

Yes, float needle is sticking. When you're done fixing the carburetor, change oil.

I would call BearTooth Kawasaki to get the new float needle. Yes, the problems are very likely to be related.

Yeah, you might be able to get it better, but only a new needle is going to completly fix it.

What bike are you talking about? A street bike with multiple cylinders/carbs? If so, replacing the needle in one carb, isnt going to fix the other one for you.

If you have a conventional dirtbike carb, and have replaced the needle and seat, and still have a gas overflow problem......then you might want to check if the float is moving freely inside the carb.
Open the carb, and with the bottom off, gently push the float up and down.
You should be able to see it pushing the needle into the seat with no resistance.

You may also want to check the float height whilst it is open.
It took me a long time to get mine set correctly after purchasing the bike secondhand. Mine was overflowing same as yours.

Also, when re-installing the carb to the bike, make sure it is in the correct vertical position (mine has small markings on the carb and rubber boot to line up).

i took the carb off today again to just check it out...the float moves freely and everything is clean as can be. After i did that i just put it back together and now it runs fine(1st gear still doesnt open up) but its ok, and no fuel is running out. Why would the bowl be gettin so full that it reaches that overflow thats way at the top of the bowl? The needle and seat should be here next week. How do i go about putting that in?
