Fuel oil drips out exhaust pipe

[Guest]

So bike fell this morning while parked!!
Now noticing fuel actually dripping out of the exhaust pipe at idle.
Was riding it earlier too and noticed some of this oil/fuel spray of the side of rear tire.

Did an oil change not that would fix the problem but it is considerably much more noticable.

So wonder just how bad is this cylinder head gasket? dirty floats?

Some good things to check from this thread.

The gas leak is "considerably much more noticeable" after changing the oil?
Was there a gas smell in the old oil?

Can you show us a picture?
I have had gas leaking from a carb due to a fall over but it dried up eventually

[tom203]

Read that link.. The fall might have damaged the petcock and/or knocked one or more fuel needle seats around.

Yes there was and noticed it was kind of nauseating.

pulled the carbs to see if anything was sticking floats and needles seem fine.

Put it back on the bike and start it up now runs like its full throttle with not throttle or choke.

[steve murdoch]

That could be throttle cables hanging up someplace.
Did the petcock check out okay?

Petcock looks fine no damage from the outside. Hoping it was a loose clamp on boot.
as for the cables checked that too chock and throttle cables are in idle with no tension. Did notice at times when turning the wheel over all the way it will throttle up, but now its throttled up anyways.

Also adjusted the pilot screw a little hoping to dial in the mixture is all it needed and not a new ignition coil.

I would check those throttle cables again. Idle increase when handlebars are turned sure sign they are being pulled. Then sticking in that position. Happened to me once

checks out idles okay
Wonder if the bit mystery oil ate uo the cyl head gasket though b/c there is smoke intead of fuel now?

Also thinking about replacing head gasket because there is some new oil I can see on gasket.

Recommendations on parts or performance parts seen ,Gasket King?
..
Worried if I have to go into the engine that much worth looking into new rings or pistons etc.

Heres a video of the problem. Leaks all the way through exhaust black fuel oil mix.

How long was the bike on it's side and which side?
I've seen oil come out the breather and half fill the airbox. Fuel could run straight through the cylinder with oil and fill the exhaust.
How long has the motor been running since it fell over and where does your breather go ?
If you have a lead acid battery it may have lost some.

Not long walked away for a minute and it had fell over.
breather tubes from carbs are just hanging there since using pods.

yes using lead acid battery now sucks as it is drippy too.

Actually rode it for about an hr before and since gotten worse seen in video.
Looks like its just bleeding out like the piston rings are gone frn 2nd cylinder. Concerned that if dirt got in there and just bored it out.

[Prescot]

Likely a stuck valve somewhere sounds reasonable.
Gas is washing down the piston rings read from this forum.
Now how to free up valves??

Is it possible that the oils is coming from somewhere like the stator cover and dripping onto the exhaust.
That leak looks too fast to be getting out the exhaust valve.
Is there smoke out the back of the muffler ?

Just checked the needle valve by tying the floats up with a rubberband and trying to blow water thru the fuel line and no leaks. So guessing it must be the exhaust valve unless it just freed itself overnight. Just to be sure want to pull a needle valve just to check it out but the pins holding the floats are pretty tight.

definitely not the stator cover it would have to travel from the other side and run down. Its making its way through the exhaust and leaking out where the header meets the muffler.
