SOURCE: fuel leaks out what looks like a vent tube coming from the carbs

Hi ...... Sounds like float levels are set too high or debris in float chamber. Switch petrol off from/at tank and drain fuel from float bowls, if you use the cap off a paint can etc you can catch it and look at it to see if any water or debris present. Retighten drain screws, switch petrol back on and see if it still overflows.

SOURCE: oil shooting in to the air box

Hello,
From your brief description I'm guessing a high mileage machine? or Previous owners have revved too much from cold?
It sounds like the engine is possibly breathing? the pistons and compression rings are worn so exhaust gasses and compression leaks past them and pressurizes the crank case sending oil out the breather, so the air filter draws it in.
If the bike is performing o.k. and you can live with it try a dribble/breather can? pop the vent pipe into a seperate container to catch it. Make sure you seal the hole in the air filter so contaminents can't get in. also the new breather needs air circulation so trial and error on a recepticle.
Good Luck!

Runs good but oil is running out of carb
I would start by removing the valve breather, it is held on by 2 screws, and cleaning it with parts cleaner, blowing it out with compressed air and let it dry.

With the breather removed, you can spray parts cleaner through the long tube running from the valve breather to the carburetor.

You may also need to drain the carburetor bowl by removing the carburetor bowl nut located on the bottom of the carburetor.

If that does not help.The next step would be,Your breater or (PCV) valve is gone. Follow the hose from the carb breather to the crank case breather. There are two screws that holds it into the valve case. Remove and replace it along witht the gasket

Sparkpluge get oiled while running
First, check the engine oil level to make sure the crankcase is not over-filled with oil. Then locate the crankcase breather vent tube. This is a rubber tube, about 1/2" (13mm) in diameter that goes from the crankcase to the air cleaner box. Or, on your bike, it may just go to beneath the engine and vent into the atmosphere. In either case, make sure this tube is not kinked or blocked by anything.
If the above items check out okay, then the only other cause of your oiled spark plug would be worn out piston rings and/or valve guides. Basically, a top end teardown and inspection will be needed.

Oil blowing out of trans breather tube
hi 81 yamaha i am concerned about the fuel smell coming out with the oil. could be the carbs flooding filling your crankcase with fuel? if not it sounds like you have blow by which would cause your crank case to be slightly pressured. this is caused by worn piston rings. do not plug your crank vent. if you leave your vent open install small filter to stop dirt from entering jim

2006 Suzuki DRZ400S oil leak from bottom of air cleaner.
Often times there is a engine breather tube that has to do with emissions that runs from the engine to the air filter breather box. This tube can in some cases blow oil through it when the engine is run hard. Make sure you're not over filling the engine with oil when you change it because this will cause the oil to "blow off" the excess and the air box is where it often goes.
There is also another possibility, are you using too much oil in your air filter after you clean it? This too is a common cause for oil in the air box, if that's the case I would not worry about it.
The last case scenario is one you don't want, that would be washed out rings which cause blow by and that in turn causes the engine to blow oil out of the breather tube which I'm confident it venting into the air box.
Please let me know if these resolve your question and if not give me more details and I will be happy to assist you further.
Regards,
RSelvy
