Question about Motorcycles
My Mikuni carbureted 113 v-twin will not quit overflowing out of the overflow hose. Took the bowl off, cleaned out and took the bowls out and plunger, no debris?? @
Hi, Wes 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.
8. Damaged petcock diaphragm allowing fuel to flow through the vacuum line into the combustion chamber.

Check the level of the fuel in the float chamber, it could be low.
You can also check the solenoid valve ....turn the ignition 'on' and you should hear a click sound at the s/valve, this proves the valve to be openning ones the ignition is turned 'on'.
Hope this helps!

The adjuster tang on the float (in green) rises and falls to maintain fuel level. It pushes on the float needle to stop the flow and drops to let fuel in. Did you loose the needle? If all parts are there, gently bend the tang upward to lower the gas level in the carb.
A “very helpful” rating for this answer? Thanks!

Tap the bowls with a screw driver handle while the gas is turned on. Your floats are sticking. If that doesnt work then you have to take the bowl off and make sure your floats are not bent.

Carb's can be cleaned, hope you didn't throw money away on a new one for dirt.
You may have dirt in the gas tank getting to the carb. If you can, remove the bowl drain, (At the bottom) and see if there is sediment in it.(dirt)
