I live in an apt too.... here is what i did. i drained the engine and let it drip till i got all i could get out. then i plugged the holes with those shop towels you can get from any auto parts store, u know the blue ones. then u can move it to where you want to (i recomend the balcony, but any place without carpet will work). Line the floor with cardboard, and keep a few shop towels around to clean up any remaining oil that leaks from the engine while u tear her down. I've found having the engine outta the bike it was alot easier and faster to work on. Just keep in mind when tourqing on it that the engine is loose, and could fall over, but that is easily avoided with the right precations.
also if you dont have any area without carpet, you can line the floor with a few sheets of plywood to give you a work area, then line that with a painters tarp, then put down your cardboard. as an extra precaution, i would also suggest having kitty litter to catch any oil spills immediatly before they run to the carpet if they are a sizeable spill.
