Question about 2006 kawasaki KX 250 F
I have a 2008 Kawasaki kx250f and when I start the bike and it is in idle, oil is leaking out of the crankcase breather tube. the bike has great compression and seems to run fine in an idle but I was just wondering if this could be a problem with having the wrong filter or if I need to replace piston ring or what but all I know is that oil shouldn't be coming out of the breather tube like that @

Hi, Anonymous and the usual suspects are:
1. Oil tank/system overfilled.
2. Faulty breather valve.
3. Engine breather hose bent, pinched, kinked etc.
4. Air filter has too much "pre-oil".
5. Crankshaft seal failure allowing transmission fluid to migrate.
6. Blow by drain tube cracked/split or filled to capacity.

Does it feel like yhe kick is even engaging and turning the crankshaft? Are you full stroking/kicking it over or short stroking it? when cold, are you using the choke. I suggest taking a compression test when it feels as if it hs no compression It could be undersized piston, rings, or a simple. good luck

There are two seals on the impeller pump. Replace the seals an the leak is stopped. Put in a new cover gasket as well.

ther is a chance that being over filled will blow out of the crank breather so drain off to the correct level if then the bike still does this then you have to high crank presure meaning the bore and piston/rings are badly worn
