Fire shooting from exhaust when idling?

[festus]

What does it mean when you have fire chooting from your exhaust when it is idling and how can I fix it? Thanks

Sounds like a very painful std you got there, i'd suggest a trip to the doc asap

I was wondering how I could get mine to shoot fire out of the exhaust!

No, seriously, my guess is your are getting some fuel in there which could mean a bad petcock.

Is it backfiring and then flaming? More details please. A picture would be cool.

It is backfireing and then popping flames. I want to ride it so bad that I can taste it. Can not afford to take it to the shop.

Check that your exhaust flanges are tight, or could be a bad gasket causing an air leak.

Did you rebuild the carbs yet?

[festus]

Have not had the money yet butb I believe that the petcock is junk. If you put it on prime it does okay, little too much fuel but when you put it on run it starves for fuel. Thought about trying an inline filter to restrict the fuel flow some and run on prime till I can get a new petcock. Money is really tight.

Do you laugh as hard at yourself as I do at you?

[argonsagas]

The petcock needs to be removed and cleaned, but it cannot cause this problem.

It appears you are getting too much fuel in the exhaust, and it is being ignited while in there, which you note as backfire. You could have a carb on one cylinder that is not shutting off when full, thus allowing too much fuel into the cylinder where it does not all get burned, but you must check for ignition and valve timing.

Edit: A compression check might also be used.

Are you running straight pipes?

[festus]

Well after alot of cussing and work we got it running good enough to ride, but it is rough!!!!! To say the least. I am going to have to rebuild the carbs. If it will make it for at least 2 more pay days I can get the stuff to redo the carbs. It spits and sputters but it goes okay. I can not wait to get it to running the way it should. I love mu ugly little bike. Thanks

i bet you CAN taste it...you sound like you're so rich its loading up in the pipe after the exhaust stroke, and its also possible you have a couple of exhaust gasket leaks too...

Where are you in Alabama? I have the next couple of weekends free, and I'm next door in Mississippi.
