I just emptied my drain tube thing by the right side exhaust on my bike and maybe an ounce or 2 of gas came out. Then a few days later I emptied it again, and the same stuff came out. My bike is also running terribly, after it warms up and the throttle is opened wide the bike stutters and then eventually dies if i continue to open the throttle. The bike is almost un-ridable in it's current condition. After about 3500 rpm the engine seems fine, but I really have to be gentle on the throttle until I get the revs up. From another one of the posts I read that the poor low revs performance might be the ignition system. Any suggestions?
Thanks, Jonathan

Re: fuel in air box, and drain tube
Have a look on your spark plugs, I guess one or two of them look really black and wet. Could be a carb or ignition problem, maybe just spark plugs. However plugs often die soon when operated in excess fuel so it might not be the true origin of your problem. Feeling on the exhaust will show you which cylinders do not work at low revs. If 1+4 and 2+3 behave simultaneous, it is probably an ignition problem.
It is quite bad to have not ignited fuel in the cylinder because it washes down the oil from the walls. So first fix your problem before you continue riding like that.

Re: fuel in air box, and drain tube
I would say carbs or a vacum leak.
Did you clean the tank out?!?!?!?!
Re: fuel in air box, and drain tube
Thanks for the help/ I've pulled these carbs off about 10 times, and I am getting sick of it. But School is almost out, so hopefully now I will have time to really figure this problem out. Thanks for the help.

Re: fuel in air box, and drain tube
My bike was acting exactly the same, and I found the problem to be the charging system.
As a test, fully charge the battery and remove the fuse for all of the accessories, then see if the engine peps up.

Re: fuel in air box, and drain tube
For a quick and dirty test, I suppose in this case one would feel an obvious difference with the headlight on or off (or even both parts by using the usual headlight and pressing high beam together) .
