or at least if anyone has any ideas why the fuel is leaking out the overflow and how to fix it.

It is the float needle faulty or dirt under the needle. If it is just dirt, you can turn the fuel tap off, run the bike until it stalls, turn the tap on again and the rush of fuel past a wide open needle may dislodge the dirt. If that doesn't work split the float bowl, remove the float needle and check it for dirt and that the tiny spring loaded plunger in the needle, is working properly. If it was dirt, it may do it again as you must have dirt in the tank.

ok I will thank you but anyways i adjusted the air mixture screw and it runs better now but still leaks. my theory is that its not the overflow its the overflow screw on the bottom of the carb bowl because i shut the fuel of after I shut it down and came back and it didn't start because all of the fuel came out of the overflow

Another thing is that when i did an oil change there was no crush washer on the drain bolt. Should i get a new washer?
and if so please send me a link or something

After leaving overnight, try slackening that screw and see if fuel runs out, before turning the tap back on, this will tell you if the float bowl has emptied overnight. If the sump plug isn't leaking oil, I would leave alone until the next oil change. If you then want to fix it, I'm fairly sure the washer is 90201-12172-00 from Yamaha dealers, though some aftermarket sellers of "service kits" include the washer with the spark plug, oil and filter packages they sell.

Check again if it is still the drain valve, or the float needle leaking. Leaking needles are common. As I wrote above, either dirt under the needle or a faulty needle is usually the cause. If it is the needle at fault, some Yams have weird needle and seat assemblies that you have to buy as a pair. If it is the drain screw still leaking, looks like you need a new float bowl. You could just turn the tap off when you put the bike away, anyone old enough to remember 1960s British motorcycles will have had to do this after every ride, as they always dribbled.
