BIG carburetor PROBLEM

[Guest]

I have a 1982 katana, and I just cleaned the carbs on it by an utlrasonic cleaner, new o-rings, new gaskets, and new jets where ever needed; But I have a problem with the chocke, The bike starts up fine on full chocke and goes into hi rpms, but within about 5 secounds after it starts up it starts to go down on the rpms with full chocke on and than dies, I restart the bike and it does not matter if the chocke is full on or part on the bike wants to die, and the only way to keep it running is by holding the throttle part way open, if I hold the throttle too little or too much it will die. But after about 2minutes of holding the throttle the bike warms up and runs like a dream, Can any one tell me what can be the problem with the chocke, is it a carb problem or air intake leak??? please help

I would look for air leaks around the carb. check your intake box, the boots, vaccume lines ect.

Sounds like your pilot circuit is still plugged. If your carbs uses choke plungers, make sure they are not leaking.

Did you adjust your valves, tight valves make for hard starting.

Sounds like either the carbs are still dirty or the mixture is messed up because the airbox is not installed or someone put pods on without rejetting. One other option is that the petcock is not flowing properly.
