Default need help kx125

Hey I just got a 2001 kx 125 for a really low price($300). Now the bad news, water in the crankcase not coolant. Worse case scenerio is what? need a new jug,gaskit kit, and reseal the water pump shaft. Thanks I tried the search but most everyone had coolant which is usaully a simple fix.

Need some clarification. Is the water in the crankwell (which is
sealed off from the transmission) or in the actual crankcase mixed
with your transmission oil?

If it's the first case, remove the cylinder and use whatever means
to remove the water. Spray the crank with a water displacing
chemical (WD-40), reinstall the cylinder and go ride.

If it's the second case, try a transmission oil change, ride the bike
and see if the problem re-occurs. I'm guessing since there is no
coolant, the water is the result of condensation or pointing a
pressure washer in the wrong place.

did they make a kx125 4t? drain the oil out of the tranny. put new oil back in, go ride it for a few minutes and drain again, if it were me id be doing this a few times.... do you know where the water came from? is it condensation? is the case possibly cracked or a gasket not sealing correctly? theres really no way for us to sit here and tell you a worst case senario on this.. if your really worried your going to to have to tear the motor down and have a look and inspect things quite thurough.
