Question about Motorcycles
Your carbs will need to be cleaned adjusted and synced, but it also sounds like you need your valves adjusted.

Theres a problem to the front carburator thus the flooding, the float pin is not sealing of the fuel supply once the bowl is full.You will have to reset the float, remove the bowl and operate the float manually( by your fingers lifting it to seal) letting the fuel to flow, if it stops thn for sure the float needs adjusting, if it doesnt stop the flow thn the pin is not sealing,you may have to replace the float pin.
Hope this helps!.

I don't know if its any help but I've fixed my Honda with similar problem. It turns out I reassembled the rich carbys air cut off valve incorrectly. Have you checked yours? I'm wondering if the cut off valves somehow affect the other parts of the carbys. Mine is running sweet now.

yes buddy to rich will cause this because the plugs will start to foul if there is too much fuel in barrel in manual it will say how many turns the mixture screw has to be out

Well there only one way the fuel can get into the crankcase and that's from the fuel tank. The petcock must be draining and the float needles are not stopping the fuel flow. Do you have a prime position on the petcock? If so do not run the bike in the position. Try topping the tank off with gas and letting it sit for a while and see is the gas has gone down and then check the crankcase and see if there's fuel in it again. i still say its got to be your petcock.
