Should I worry ?!?
Here is the story . . .

Getting daughter's GS500 back to running
and checked the oil reservoir dip stick.

The level was way above the 'Fill' mark,
looked very thin and smelled of gasoline.

Pulled the drain plug and what came out
looked like the bike had diarrhea !!!

Almost filled a gallon container when the
bike takes only 2.4L of 10W-40 oil.

Since the bike was only started for a few
minutes from storage, did the engine sustain
damage, or just clean-out the oil sludge?

Your advise is greatly appreciated !!!
(except from trinausmc who will rib me endlessly!!!)

1st. Try to figiure out why the fuel seeped into the crank case.
Petcock left on? Was it left on the PRIME position?
Dirty float needle and seat? Determine why this happened.

then...
Try it. Leave the fill cap open, drain plug out and spark plugs out.
Let it vent off any remaining fuel.
Then squirt a little oil into the cylinders.
Roll the engine over by hand. Do this while the plugs are out.
Stick it into 5th gear. Turn the rear wheel by hand. This will work oil back on to the cylinder walls and rings.(it got washed off by the fuel leaking past the petcock or needle and seat).
Swap the old oil filter for new.
Add the new oil . Warm it up ez.
NOTE: you will get some smoking at start-up due to pre-lubing the cylinders.
Go for a ez ride. Listen for any odd unfamilar noises.
My .02 cents

See? I don't have to do anything for you to get ribbed! Jimmy has this!

But yes, I suppose you're right, although I would rib you regardless of this thread, just sayin'...

Oh, and I have absolutely no advice for you regarding the motorcycle

The only thing I could add to what James1300 said is; Never ever start an engine without first checking all the fluids...AJ

There are quite a few of us around here with GS500's.

Usually we hang out on www.gstwins.com - probably the best site for anything and everything GS500.

It is quite possible someone left the fuel petcock on PRIME (thinking it was OFF) and the carbs flooded, leaking gas into the cylinders and into the oil.

FYI: Petcock is vacuum operated so there is no OFF position. It has ON, RESserve and PRIme. Leave in ON when bike not running as there is no vacuum so fuel is off. PRIME bypasses the vacuum and dumps fuel into the carbs - used when you need to fill the carbs after working on them.

I had an issue like this with a 96 CBR900.
The petcock was bad with a pin hole in the VAC diaphragm.
It filled two cylinders up to the carbs. The head was full.
Drained at least a Gallon and a half of fuel/oil out of the crank case.

I did what they^^^ said.

Drained it and let it set for a few days. I had other work to do on it.
New filters, oil and cleaned the plugs. Of course I replace the faulty petcock.
After all the work was done it ran great.

This was the second bike with a crank case full of fuel. The first was a Ninja 250.
It run fine with no issues after it was all cleaned up. That was 8 or 10 years ago and it's still running fine.

Like they said. Clean er all up and should be fine.

THANKS to all for your advise.

I am not sure of the petcock since
the tank was removed and petcock
was in the ON position when found.

Bike drained, dried out and ready
to be refilled with oil and tested.

There is the West Seattle GS500 Club. We can help if you bring it to West Seattle. We've got whatever spare parts might be needed.
