I started having problems with my bike flooding like crazy. I would remove the air filter and find the left two cylinders flooded and right two cylinders dry. Cleaned carbs, rode for a few minutes shifted into 5th and the bike flooded out again. So i replaced the float needles, checked the floats, reassembled and now is flooding almost wose. The only difference is the cylinders don't appear very flooded, but the hose comming off the air sylinoid valve is pouring out gas. I tried bypassing the fuel pump, same thing. I havent been able to ride this bike in weeks, anyone have any suggestions??

 

Also just now i went to start the bike and a stream of fuel shot out of a small brass needle comming out of the side of the engine right by the throttle position sensor. I believe this needle was capped off by the previous owner, but i have no idea what could cause fuel to shoot out like that. It must have sprayed 10 feet! If this wasn't my bike it would actually have been pretty cool lol

 

Just check you may have swapped the fuel and air intake hoses on your carbs.(That will blow out fuel everywhere) but if that’s not the case…

I had the same problem. I discovered that one of the seats (or guide holes) of the float needles had some sediment in them that cause the needle to get stuck halfway sometimes.
Clean the seats properly with an ear-bud and some methanol or carb-cleaner.(They fit exactly in there and work like a bottle-brush)
You can test the floats by turning the carbs upright, then while blowing thru the fuel hose turn them upside-down. The pipe should block completely without any air leaking thru. If it does, try and listen which carb is leaking and clean it again
Do this a couple of times to make sure the floats are working smooth.

 

Ok, I found that i had 2 floats that were hanging up. I cleand everything and got the floats moving freely. I put everything back together and tried starting, no go. So I thought a little and figured out that the cylinders were still flooded and the plugs were fouled. I removed and cleaned the plugs, and now have the bike sitting with the plugs out and everything airing out. My question now is should i be able to see fuel going into my carbs by looking down the stacks when cranking. Because now that i changed the needles and everything i looks like the carbs are not getting fuel. But the fuel pump is working and i can see fuel comming through the fuel filter, and its not leaking anywhere. It is possible that my bike has been running very rich and i'm just used to seeing more fuel in the carbs, and now the floats are working right. What do you think?

 

Nevermind, I figured it out. Thanks for the advise!
