    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.

I have an 82 GS750t that has four lines the two on the outside I know are vent lines and the inside two connections to the peacock now I have what I can only assume is the vent tap for the tank connected to one of the vent lines and have one line that looks like it doesn't connect to anything or an I missing a connector because everywhere I look it says to route on the framebut that seems wrong so what exactly am I supposed to connect the vent lines to
 
Go to bike cliffs site. It has a section called "where do these hoses go?".

The vent lines coming off the carbs go up under the seat where there is dead air. They usually follow the frame to a spot under the seat on either side. Their basic function is to equalize the air pressure in the fuel bowls allowing fuel into the bowls. The ends of the vent lines are left open under the seat area. The main fuel line that comes out from the middle of the carb gang goes to the petcock and the smaller line that comes off #2 carb to the vacuum nipple on the petcock.

The rubber line that comes off the tank is a not a vent line, it is an overflow line in case the seal around the fuel gauge sending unit springs a leak, It is routed down to dump on the ground, It should hang about 3-4 inches under the bike and keep it away from the exhaust.
