nah man all of the plastics are off of the thing and the two vents are clear

 

its almost seems like the choke is stuck open and its causin it to just dump fuel into it

 

I think you may have switched your vacuum lines from the tank to the carbs or the fuel petcock diaphragm is ruptured, dumping fuel in from the carb vacuum line. try disconnecting the vacuum line that goes from the tank to the carb/ intake boot. see if fuel is coming out of it. Try strarting the bike with it disconnected and check for fuel again.

 

nah i didnt touch any of those. i didnt remove a single hose. im taking the bike to a a guy my buddy knows that builds all of his race bikes.

 

It may not have anything to do with your oil change or you not disconnecting any lines. It just failed and by coincidence happens to be after your oil change. It is also possible that your float valve is stuck open. Try what Evil636 suggested with draining the float bowl. Check that vacuum hose from the tank to the carbs. It causes suction on the diapragm which allows fuel to flow to the float bowls. If the diapragm is ruptured, it'll dump fuel in the cylinder of the one with the vacuum hose attached. You can also check your plugs to see which cylinder is running rich.

 

well. im gonna pull the tank off of it and see what i can see. i dont know **** about fixing bikes. plus i just wrecked my truck last night. so i gotta get the bike fixed so i can get my truck fixed

 

got the bike started today. the oil i used was too thick. i drained the 20-50 and put in 10-14 and she runs like a dream...minus the ehaust leak. ill fix that monday

 

cool beans bro...

 

That's wierd that it wouldn't start because of thicker oil; doesn't make sense withe the backfiring and flames in the tailpipe. I still think that you may have had something stuck in one of the float seats that was keeping it open and now got freed.

 

BTW, I'm glad to hear that it's running.
