How do i change clutch release arm
I believe the arm is on top of the case on the left hand side attached to a shaft that goes into the case. It also may have a bolt in the side of the case below the arm that has a machined shoulder on it to retain the shaft from pulling out. If it does, remove it.If this is the way it's set up, it actuates the clutch thru a rod that goes all the way across the motor inside the hollow shaft that the clutch is mounted on. I don't have specific experience to the 250 KX, but I've been in the little ones and that's the way they're set up. So here's what you do-
Drain the gear oil and remove the round clutch cover on the right side of the bike. Remove the 5 or 6 washered bolts and the springs from the clutch pressure plate. Remove the pressure plate and you'll see the clutch lifter-it's a short rod with a flat bearing on it located in the middle of the clutch shaft. Remove it and using a small magnet tool go inside the hollow shaft and retrieve the actuating rod. There may be a ball bearing with it as well, although I don't think there is in that bike. Anyway, don't lose it if it has one and pay attention to which end of the shaft goes to the clutch arm. You can now replace the arm. When your putting it back together, rotate the arm with your fingers and make sure the lifter is moving up and down before you put the pressure plate and springs back in. Good luck!
Hi, my 1994 KX 250 will not engage 4th gear
The worn shift fork is the problem. Normally a shift fork will never show any wear. When a fork gets bent is when wear begins to show. If a good shift fork is set side by side with a bent fork it is very hard to see any difference. The bend is so slight that it is usually impossible to discern. Put in a new fork and the shifting problem is history.
Now would be a good time to install new crank bearings and new crank seals as well.

How to find out compression problem on a 2003 kx 250
Just cause the piston looks fine dosent mean the rings are still good did you do a compression test if you don't have one buy one they are great to have with 2 stroke bikes put the cylinder head back on and cover spark plug hole with finger it should first **** a bit then should blow finger off the hole the compression should be greater than 120 psi of a 125 not sure on the 250 rule of thumb if you have less than 120 your piston or rings is pooched..
99kx250 will not start getting spark not sure what
if it's getting spark but not starting, it's likely that the carburetor is plugged up.
Spray some carburetor cleaner down the throat of the carburetor to try to clear the jets.
Otherwise, may need to rebuild carburetors, especially if the bike has been sitting around for over a year.
good luck on this one.

86 kawasaki kx250 rich mix problem
"Learn to like smoke for awhile. Smell the aroma". Pardon the humor. I couldn't resist. Chances are there is oil built up in the crankcase. It is going to take some time for the oil to
dissipate. How long? I don't know. It all depends on how much is in there. Cleaning the muffler is no help since the oil burning is coming from the crank not the muffler. If you are careful, and keep a
vigilant eye, you could cut the gas/oil mix in half to 64 to 1 instead of the normal 32 to 1. That would mean only 2 ounces of oil per gallon instead of the normal 4 ounces. Let the crank add the rest. This will help burn the crank oil excess, but BE CAREFUL. When the crank drys up you had best not ride until more oil is added to the gas.
A “very helpful” rating for this answer? Thanks!
