Dumb question...

[menteerd]

So my bike wont start, then it will start for a minute but only go up to about 5000rpm and wont idle without dying. I took off the gas tank to check the fuel delivery (gas, air, spark) and gas was free flowing out of my petcock. this is my first bike and I am doing a rebuild of it so I am not sure how they are supposed to work. Is this bad? I would think that too much fuel COULD cause my problem. Do I need to replace the petcock? Sorry for the long thread. Thanks for the help.

Rebuild the petcock. Fuel should only flow in PRIME or when the bike is running.

You don't know your head from your ***, that's what's wrong with you. Yes, his petcock needs rebuilt. The carbs may be fine, fix the petcock first.

okay

arsenic, your posts crack me up.

As redkat was saying:

The petcock has three different positions, Reserve - pointing towards the front end of the bike, On - pointing down, and Prime - pointing towards the rear.
Fuel should only flow from the prime position without vacuum being applied to the petcock, (engine running). Rebuild kits are cheap, about 30 bucks.
For more info - search. oh wait, here i found it.

Damn, too late!

Petcock won't cause those symptoms. Sounds like a big vacuum leak to me.

big vacuum leak?? so flooding out the carbs wont cause the bike not to start?....shucks...where do i look for the vacuum leak????

I'm with you, there are other things at play. HOWEVER, you know the petcock is bad. Fix that first than start troubleshooting other things.
