SOURCE: oil blowing out of trans breather tube
hi 81 yamaha i am concerned about the fuel smell coming out with the oil. could be the carbs flooding filling your crankcase with fuel? if not it sounds like you have blow by which would cause your crank case to be slightly pressured. this is caused by worn piston rings. do not plug your crank vent. if you leave your vent open install small filter to stop dirt from entering jim

I think you already found your problem. Too much oil can push out when hot. Set your level and clean up the mess, you should be OK!

it's probably leaking from the carb and down the cylinder into the crankcase.
it is probably due to a stuck float in the carb. take the float bowl off and make sure it is clean. the float can also be full of gas not letting it float up and stop the gas flow. the carb will fill up and leak wherever it can which is likely the case

This is an age old problem for the Harley engine. In you 89 model, the crankcase breaths from behind the oil pump through a tube that runs to the backside of the air filter assembly. Most people that I know, simply remove the tube coming up to the air filter and block the hole in the air filter assembly backing plate. At the breather, they run a short hose to just behind the transmission and cut it off there. This is similar to the earlier Shovelhead engine and the way it breathes. In 1994, Harley went to the "head breather system" which was better but it still gets oil into the air filter assembly.
There is one thing I saw on the aftermarket assessories market once called a "CatchCan". The breather tube ran to it and it seperated the oil from the air and the held it in a small container to be emptied on a regular basis. I have never used one nor have I ever seen one so all I can tell you is what the book said. Matter of fact, I cannot remember where I saw it now. Custom Chorme catalog, maybe. Good Luck, Steve

If it has not been over filled with oil the it will most likely be to much blow by caused by the compression rings wearing out.
Do a compression test and check against the acceptable figures from your manual or a dealer.
If the compression is to low you will need to do a top end rebuild.
Testimonial: "thanks for the advise. i know the oil level is correct so i guess , its going to need rebuild..:("
