kawasaki KX 250 - Recent Questions, Troubleshooting & Support - Page 6

hi, this could be as a result of mall adjustment, or simply clutch plates stuck together as a result of the machine standing, normaly running the machine and using the clutch is enough to cure this,otherwise you may havee to remove the clutch plates and check for worn or distorted plates, it may also be that the clutch basket is worn not alowing the full release of the plates, check for exsess ware in the form of groves cut by the plates in the outer and inner basket.
thanks for using fixya

The kx 250 has quiet a large frame for its size, a good match up engine would be an honda xr 250/400/600 engine. This should all fit pretty neatly, with minimal welding, maybe the odd bracket. If you are wanting to stay with a two stroke, it will be very hard to find an old air cooled engine that hasn't done a lot of work and is needing money thrown at it. Sounds like a good project! Air cooled engines are your best bet, things start to get tricky with mounting radiators e.t.c

hi, you do need the use of some special tools, to change a conrod-big end kit, presuming you have the engine striped and the crankshaft removed, i would take it along to a recomended garage to carry out this service, paul

You should contact Kustom-kraft.com. They will repair yours. I've sent them 5 so far, and all have come back perfect. $65 for bore/hone.

Head nuts 18 ft-lb (25Nm), cylinder base nuts 25 ft-lb(34Nm)

Check your engine and transmission oil for anti freeze. Also check to make sure your engine breather is not plugged. You probably have a leaking water pump seal , that is allowing oil to get into your anti freeze through the transmission. Normally when this happens the anti freeze goes into the transmission oil.
If there is no anti freeze in the lower engine or transmission , then the oil is leaking from a high pressure oil line going to the head to the cooling chambers filled with anti freeze. This means you probably need to replace your head gasket on the motor. While you have the head off check to make sure that the head has not warped. If it is warped it may have to be machined back to flat or replaced.

You mix with gas 40 to 1 ratio will work. I’m happy to assist further over the phone at https://www.6ya.com/expert/michael_18b4936ebf017b21

there is a wierd shaped spring that activates the ratchet, when you kick, this may be installed incorrectly, if the gears and ratchet look good

Same thing I had happen. Your friction disks and plates are normally joined via spring pressure and unjoined when you pull the lever. In my case, the bike had set for so long, the plates had become chemically bonded together and stayed locked tight clutch in or out no difference. What I did was remove the clutch access cover and physically separated each plate one by one and reinstalled. After that, it worked great.

Here is a generic diagram of a clutch, should explain it.

try craigslist or call your local motorcycle salvage yard good luck

how do i set timing on a kxf250 2004

Insert a screw driver to the carb's adjuster screw. Turning clockwise will increase the flow and turning counter clockwise will reduce the flow.

mineral motorcycle oil SAE10W40 should do. Cheers

look up your particular model and year.

1-2.5 inches of deflection.

It is not necessary to change the oil after every ride. Unless you are talking over 1000 miles each ride. A little water in the oil will not hurt. Especially if you are going to rebuild the engine this winter. And you can use any gear oil that is 80w or higher. Walmart sells some in a blue bottle. I am sure that you have a blown head gasket. You can try some radiator stop leak in the radiator also. This may seal the head gasket temporarily.

im presuming its a two stroke it sounds like the two stroke oil pump-which is starving the engine of oil-change the pump before u destroy the engine-this is not a maybee,your engine will need a total rebuild if u carry on riding with this problem!!!!!!!!!!!!!

go with your own u will never wrong
