It sounds like there is too much pressure in the crank case, causing oil fumes to be cycled through the breather. High pressure in the crank case is caused by worn cylinder bores, allowing 'blow by'.

You are either running way too rich of a mixture, or your rings have gone bad and you are drawing crank case oil into the cylinder, determine whether the oil is mix or crankcase oil, either way you have an issue, are you using too much mix oil? are you losing crank case oil, something somewhere is telling you where the problem is.
Could be carb problems. The cylinder is getting to much fuel and it is going past the ring into the crank case. Try rebuilding your carb, could be out of time : check to make sure the engine is timed properly.
your crank case does not take oil at all. your transmission however will take usually 1 to 1.5 quarts of approved transmission oil.
Rarely a cylinder will fill with fuel from a seriously flooding engine, making it impossible for the engine to crank. Does the engine TRY to crank? Is the starter engaging? If it's truly filling the cylinder with fuel you should be able to pull the sparkplugs and crank the engine. When that happens fuel should come out of the sparkplug holes. Make sure that you have a couple helpers and some fire extinguishers with you just in case since you don't want that much fuel igniting under your hood. Admittedly, it's an off-the-wall idea, but it actually can happen. If that isn't your problem, go after the individual problems. Replace the "needle and seat" in the carburetor to solve the flooding problem. If the cylinder isn't filling, track down the starter problems. The fuel can wash away the oil on the cylinder walls and rings. Best to remove the plugs and shoot a little oil into each cylinder, unit you can easily crank over.
It says the oil cap. On the crank case cover. I have the same bike, but I can't remember off hand the exact amount. I believe it is measures in ml on the crank case.
New? Rebuilt? Used?
Physical damage to a cylinder is seldom repaired. More often the motor is replaced.
If the heads, cam, crank, and block is good then you are looking at about 1500 professional and 700 do it yourself
