    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. 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.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    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.

last night i pulled the tank off my project gs750l (its my first project) I tried sucking on the vent line with my mouth and ended up with a small amount of gas in my mouth and no fuel flowed out of the main line in the run position. Will the bike run if I just leave the petcock in the prime position? I would like to get the bike running before spending money on a new petcock.
 
In the "Prime" position the petcock valve is held continuously open and fuel should flow to the carbs unimpeded. Be careful that the carb bowls don't overflow when the engine is off.
In the normal or "Run" position the diaphragm is what activates the valve and therefore needs vacuum to do this. I bought a ner petcock from Bike-Bandit US$50.00 for my GS650 project as the tank came minus this device.

Yeah, you don't want to flood your crankcase with a bunch of gasoline. I'm guessing your bike is a 1980 model but petcocks and electrics seem to be the major "biggies" with these wonderful, old bikes. Consider a Pingel and do a search to see what it's all about. Good luck!:-D
