If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I have an interesting thing happening with my 850, I try to start the beast and it just cranks over and no fire this with the fuel on if I walk off and wait 20 to 30 minutes with the fuel on she crank right over and fires run good.
Beside the petcock what else could be a problem.
 
Kinked fuel hose, petcock, blocked inline filter. Other than that there are no other real obstructions for fuel. Once it's in the carbs there would be different symptoms. HTH

Changed the petcock this passed weekend with a Pingle made problem worse now at a complete lose at what's going on
 
If you ride the bike with no problems and then shut it off, there should be plenty of fuel in the bowls for the next start up. I don't know why you'd have to wait.
Anyway, since you have a new Pingel and you've capped off the vacuum port at carb #2, (right?), then first try cleaning the gas cap vent very well. There should be a ball you can hear rattling around if the design is similar to mine. This vent design can get clogged and fuel will not flow well from the tank to carbs.
If this doesn't help, next thing would be to remove any aftermarket filter you may have. The fuel valve screen is all you need.
Next would be the passages to the float chambers are partially clogged, or the screens above the float valves are clogged, or the floats valves are sticking and not allowing full flow.
If the gas tank has any rust, it needs to be repaired first or this will happen again.
 
What is this vacuum port on carb #2 for? I just rebuilt a set of carbs that had this open port, and I didn't know if it was supposed to go somewhere, or if I should just block it off????

??? I believe that #2 vacuum port connects to the vacuum port on the petcock....or are you using a Pingel?
