When I turn the throttle the bike goes out...
 

I cleaned the carburetor...3 times... :)
any ideas?

Assuming your float is working properly in the carb, it could be that the diaphragm in the fuel petcock isn't responding to the call for more fuel. You might take the petcock apart and make sure there are no tears in the diaphragm.

Hard to diagnose some things over the net. good luck.

You might want to try starting it with the petcock set to prime. That will tell you if your petcock is starving the carb for fuel when you throttle up.

the manual says the airflow should be 1 1/2...I think it's should 3 - 3 1/2? how many do you turn yours?

Was your bike running lean to begin with? An indicator would be your exhaust pipes turning blue where they come out of the head. If that is the case, I would bottom out the screw and then turn it out 3 full turns. If not running lean, I believe the factory setting was about 2 and a half to 2 and 3/4 turns out.

Let me know how things turn out for you. By the way, what year bike is it?

My bike is a 2009 and I had to turn it out about half a turn to richen it up a bit.

Hello,
mine was set to 3,5 turns and I drove her for 3 years without any problems.
she's 2003

Did you also check out the fuel petcock and also check the vacuum hose going to the carb to make sure it hasn't collapsed.

Another thing to check is to make sure the choke is working properly. Does it die from idle if you engage your choke or rev up?

Running out of ideas to help you out. Hope you get it figured out. Let us know what you ended up doing to make it run properly.
