Start by cleaning the carbs, and then check your crankcase breather system. You have a 1/2" hose from the rear breather to the airbox. The hose connects at the center top of the box. Remove the hose, and turn the engine over with the starter. If you feel pressure pulses from the hose, pull ONE spark plug at a time, and try again. When you do NOT have a pulse, that is the problem spot. You may have cracked a ring, or put a hole in the top of a piston. That is the WORST it could be. As I don't know the history of the engine, it may just be too much oil, and the high speed caused it to blow out the breather and choke off the air to the carbs.
Let us know what you find, and go from there....

How full is the oil.... and are you sure it was oil that was coming out? When you check the oil, the bike has to be on it's centerstand or level; if you check/add it while on the sidestand, it's overfilled. If you had a carb float stick open (a common enough problem), you may have poured enough gas into the motor to raise the oil level. Or you may have simply been seeing raw gas. Will the motor still turn over? What do the plugs look like? If it's seized, it may be done...

Check the oil level, and see if the engine oil smells of gas. Do the checks Ray mentioned...

My guess is that you've had a drastic mechanical 'event' occur after a high-speed burn. I'd say you've blown a piston, or cracked a piston ring or two.

Remove the plugs and turn the engine with your finger firmly over each plug hole in turn. I suspect you may find very poor/zero compression on one cylinder.

Try this and report back!

Do the checks the others have suggested. It can be repaired, no matter what the situation. It depends on how much you are willing to put into it both monitarily and labor wise. Parts are available on this forum or there are links to where you can obtain them. In the end, if you decide it's not worth the money or time, I'm sure there are people on here, like me, that could use some of your parts for our own repairs so don't just junk it.

Ive done a total tear down of the carbs 2 weeks ago they are nice a clean also added fuel filters as per thread on this website as for checking oil and spark plugs ive been meaning to do that I will have a chance to do it today after work im sure its oil smells and feels like it as far as condition of the engine I dont know ive only had the bike a year but my guess is she had a hard life thanks for all your input ill let you guys know

I have seen excess fuel in the exhaust run out looking black like oil. But form what you explained, coming out the air box / carbs as oil, that would indicate it is oil. And if it is coming out both like that, my opinion is your going to find a hole in a piston.

Ok ive done compression readings on all my cyilanders here are all of my redings
#1 59psi #2 61psi #3 0psi #4 90 psi also spark plug 3 had all the oil in it very fouled plug too one strange thing I noticed with 3 is I got no reading at first but anyone who has used on of these gauges know to put a little oil in the cyliander to get a better reading sure enough I got the needle to jump as for the oil in the crank I was low about a quart and a half low pistom movement looks to be alright as far as puting my finger over the spark plug hole very very little pressure behind my finger

looks like ur going to need to pull the head off,
when u do and before stripping the head, tilt the head
on its side and pour petrol into each port and see if u have
any leaking/seapage of the valves, then flip it over and do the
same thing with the other side.
if theres no leaks/seapage then
check the pistons, if theres no obvious holes in the top
have a look for any cracks.
if theres nothing wrong with the tops of the pistons ull have
to take the barrels off and check the rings.

I had a hole in my #3 too. Compression went to sh*#. pulled my head off and replace that psiton with a used one off ebay and put 4 new sets of rings on while I was in there. The only thing I wish I would have done during that repair was to replace the bas gasket under the jugs. the RTV/gasket sealer I used is just not holding that well and my bike now leaks. I've got little puddles in my carport and my pant legs get little stains on them now.
Here's the thread for my repairs.

Good luck and ask all those here for advice.
Did mine in one weekend.

Are you doing the test correctly with the throttle held wide open, Other plugs out and 4 pin plug at TCI disconnected? If not that would explain the readings.
