So got it on the lift today...The oil does smell gassy and is very thin...Looks like it's an accumulation over time....
I'm suspecting too much fuel pressure....I have a small electric pump , that is supposed to be under two pounds...But, I don't have a fuel pressure gauge on the line, and can't be sure if that's the problem...
Tomorrow, I'm going to only use the electric pump to get the gas to the carbs (tank in rear, engine in front)....Then turn off the pump before starting the engine...
The original fuel pump that was on the bike, was working, so it might be enough to draw from the tank, once primed.....
Of course, the oil has been drained out.
I hope this solves the problem.
Thanks for the help.

Has it got a petcock? Was it on or off? Even if on, carb intake needle & seat should have prevented fuel flooding CC. A little trash on a seat will prevent needle from working to stop excess fuel in floatbowl.

If it was too much pressure the engine would be flooding while running. Turn the petcock off when parked.

What year engine will help with diagnosis. Float needle and seat are likely cause but could be elsewhere. Failure to remedy this can result in a bent rod. As mentioned, turn petcock off always. Bump the starter with the kill switch on stop a few times to ensure it’s clear. That will ensure you don’t get one or two cylinders firing to add to the force of a piston coming up to a hydrolocked situation.

What can happen is the intake valve on one cylinder holds a few ccs of fuel in the port and runner. When you go to start it, the valve opens and the liquid flows into the combustion chamber. When it closes and the piston comes up, everything comes to a rapid halt.

If the motor was shut down with intake and exhaust valves open, the fuel goes in the chamber and drizzles out the exhaust. Some will get past the rings and into the crankcase.

Hmmmm...Didn't know that , but the petcock is on the tank, under the body where it can't be easily reached. I now remember that I used to shut the petcock off on my 750, after every use.
This is a '79 1000 engine....
Now you've got me thinking about adding another access port on that side of the car (I have a couple service ports), so I can shut the fuel supply off....
Either that, or put a second petcock near the engine.....

I did run the starter with the plugs out, pump off, and nothing came out of the cylinders on that side.

This is useful info...Thanks

How about 1 of these?

If this doesn't do the trick I will have to find a plan "B"....

I did some more searching...I was looking for a way for oil to end up under the engine in this quantity...For the first time, I noticed the hole under the water pump had some oil coming out of it.....(Just a little, but there shouldn't be any, right?)
It would have to be a REALLY bad seal for this much oil to be expelled, wouldn't it? I just don't see any other outlet for the oil....
That being said, would gas in the oil cause it too seep past the water pump seal in this amount, or am I dealing with both a bad water pump seal and too much fuel pressure?
Also stuck a small screwdriver in the hole...Lots of grease and liquid oil....
Thanks for the input
Edward

I don't think you have too much fuel pressure, just leaking float valves. The thinned oil will leak worse but you probably still need a new water pump.

The float needles could be leaking, but excess fuel pressure from the electric pump may be the culprit...I just purchased an in-line pressure gauge...I will be looking for less than 2 lbs , preferably 1.5 lbs or less....
While I hate to take on such a project , before I've really had time to get this on the road, looks like I will be replacing the water pump and all associated gaskets....
If anyone has any tips, other than what's in the Haynes and Clymer manuals, please let me know....
Thanks again.
