Update on my first bike - 11F

(snip) AND possibly re-contaminate your NEW ENGINE OIL with fuel again! Leaking petcocks themselves are not a real problem IF your carb floats and valves are working properly.

Sounds like you need a trip into the carbs to clean and check things out, the float needles and seats, etc.!

T.C.

There are some quick-and-dirty ways to ensure that the petcocks don't overfill and drain into the carnkcase. I see you have a standard 79F. You can first test for leaks by getting some lengths of hose,
(1) disconnect the fuel line from the petcock while the petcock is set to "ON." This is the position that should only flow when vacuum is applied to the other nipple.
(2) check for leakage out of the petcock nipple.
(3) Do the other petcock the same way.
(4) If there is some leakage, you can leave the leaking side's carb fuel line disconnected and cut a small length of tubing, find a bolt that will plug the end of the length of tubing, and plug off the offending petcock with the hose/bolt plug.
This will buy you time until you sort things out. At least it will prevent contamination of the oil.

Now - the left petcock was completely disconnected as I noted in my first thread and we tried to reconnect it but the hose was way too tight (it's supposed to be tight but not impossibly tight) and so we're not sure about that one.

Standard petcocks hook up to two lines. The fuel line is the larger and comes off inside (backside) of the petcock and down to the lower T fitting between the carb pairs. The smaller line is the vacuum line going from the fitting facing forward to the intake manifold. With the engine running vacuum opens the petcock. You may have switched these.

Gas in the oil can also be due to leaking petcocks as well as carb float needle seats as discussed.

Just picked up a Clymers manual. I drove the bike around a bit before it started storming this week and I get lots of burps and pings but otherwise the performance is good. I'm moving in the next few months and I'll finally have a garage so I can comfortably go through every procedure listed in the manual. Thanks for your input everyone.
