2006 Kawasaki KX 250 F oil is leaking out of the crankcase breather tube

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.

SOURCE: kick start has no compression but runs fine once i get it going

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

hi
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
thanks jay

2002 Kawasaki VN 1500 Vulcan Classic oil blew out at the breather hose when cranked


Hi, Anonymous it's called "WET SUMPING" if left sitting for weeks or months will eventually let the oil tank contents drain pass the oil pump check ball and fill up the bottom end of the crankcase when the bike is started the excess oil will gush out of the breather vent and if routed to the air cleaner will also flood the filter. This messy condition will continue until the bottom end is forcibly emptied by the flywheels or manually drained if there is a plug. There are 3 options you may want to consider:
1. Drain the oil tank before storing the bike.
2. Replace check ball and resurface seat in the oil pump.
3. Install inline ball valve shut off in the feed line to the pump.

Hi, Anonymous you have a blown head gasket for this scenario you will need your service manual that has all fastener torque specs and a wiring diagram on the back pages, parts fiche, and owners manual if you can't find the best tool you ever bought for your Kawasaki, despair not, for a mere zero $0 you can download another one.

2008 Kawasaki Vulcan 1500 Classic oil level check


Hi, Todd if you are experiencing excessive oil coming out of the crankcase breather or air filter please drain all engine oil and replace half of the same oil that comes out. Many riders are overfilling their oil system because they do not know how to properly read their oil site glass or dipstick. The following procedure works on nearly all 4 stroke engines but to be on the safe side you should refer to your owners manual. Use your center stand if you have one.
1. Bring the engine up to operating temperature or let idle for 5 minutes.
2. Turn off your engine and let it sit for 2 minutes, this will allow the oil from the top end to drain to the bottom.
3. Hold your bike straight up or on the center stand and wait 2 minutes for the oil in the bottom of the engine to be level in the sight glass or on the dipstick.
4. Your oil level should be between the top full mark and the bottom add oil mark.
5. Never overfill your oil system it will cause problems:
a. oil leaking out of exhaust pipes.
b. oil leaking out of breather pipe/hose.
c. oil carryover into the air cleaner.
6. Your oil site glass must "NEVER" be completely full or empty drain or add oil as necessary.
7. Your oil dipstick must "NEVER" be over the full mark and should never be below the add mark drain or add oil as needed.
