Question about 2005 Yamaha PW 50
I could not get the bike to stay running, so I cleaned the carb. Bike fired up and ran great, but then noticed that gas was pouring out the over flow. I have pulled the carb apart again and have come to the conclusion that the needle valve is not seating. Could this be the problem?

Hi, Anonymous "ABSOLUTELY" and the usual suspects are:
1. Damaged or restricted fuel tank venting system.
2. Loose float bowl screws.
3. Damaged float bowl o-ring.
4. improper fuel level in the float bowl.
5. Worn or dirty inlet valve or seat.
6. Damaged or leaking float assembly.
7. Particle contamination in inlet fitting cavity.

I have had several bikes in my time. and keeping the carbs syncranized is very important. Did you put aftermarket pipes on it? try rejeting the carbs up 2+mm that may help the fuel air ratio?

Theres fuel starvation, the carbs are not getting required fuel in other words the float chambers doesnt get the correct amount of fuel .
Check the fuel flow from the petcock to the carburators.
Check the float pin and adjust accordingly to get the right level inthe float chamber of each carburator.
Hope this helps!
