On my Suzuki RM125 and on my KTM there are two plugs. The one on the flywheel side is the drain. The one on the crankcase side is to tell if it is full. Drain it on the flywheel side, and then put the plug back in tighten, (but not too hard you don't wanna strip it.) Then go to the crankcase side and take the plug out but be ready to put it back in fast. Take the cap off the crankcase cover and pour the oil in untill it starts to come out the plug hole, (on the crankcase side.) Thats what I do on both of my bikes. My buddies Honda CR 125 is the same way. I'm guessing Yamaha is the same way.

If a two stroke racing engine is completely drained of oil, then use a ratio-rite or other measuring device and add the specified amount of oil to the fill location(see if it is stamped on the clutch cover in cc). If there are no seals leaking and no leaks from a failed gasket then put the measured amount in and its good. It does not burn any oil so where is it to go. Change it often depending on how hard it is ridden. You are trying to get the most life out of your clutch and lubricated the transmission. There are many light weight gear oils(80w "not hypoids" settle down all you motorcycle guys who are not two stroke motocross guys) that are ideal for your bike. Many times the manufacturer of the bike will not list this as the oil in your bike because their oil line does not offer such. Start subscribing to a motocross magazine and read about tests of products available for your bike.
buy a service manual to get familiar with your bike.

Go to - your bike - Crankcase - #7 is the drain bolt.
After draining, install a new sealing washer if necessary.
Fill the crankcase with quality, brand name, 4 stroke motor oil.
Go to - Crankcase Cover - #10 is the fill cap - #12 is the oil level check bolt.
Check the oil level with the bike straight up and down (as if you were sitting on it).
Remove the oil level check bolt (you can tell which bolt it is cause it has a sealing washer on it).
Fill the crankcase until oil starts to come out of the hole.
Install the check bolt and run the engine for a few minutes.
Let the engine cool down for a few minutes.
Remove the check bolt and add oil until it drains out the hole.
Let it continue to drain until it stops, then install the bolt.

two stroke right?
well the only oil you can change is the gearbox oil and there should be a drain plug at the base of the gearbox. Undo. Drain oil. Replace drain plug. Fill gearbox with fresh gearbox oil to level specified by yamaha.
(You can dump the fuel oil by unscrewing the reservoir and emptying)
