    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.

How do I tell sub model of my 80' gs 750? I'm not sure if it's an E (t or x) or an L (t or x)
 
Thank you, I am trying to get a pet cock for it and there are different part numbers.
 
Maybe you could answer this question.

I've got a 1980 gs750 that I recently bought. My issue is that it runs, but after a few short minutes fuel pours through the valve cover breather into the air box. There is an aftermarket pet cock put on after the original. I've heard that if the original is bad, that could cause the problem (vacuum issue). I'm wondering if you guys can either confirm or throw out other ideas.

Fuel pours through the valve cover breather into the air box? That can not happen. Maybe through one or more of the carbs throats into the air box but not through the valve cover breather. You better look that over very carefully. Sounds like your floats are way out of adjustment or your carb vents are ? Check your engine oil to see if it smells like gas. If it does STOP RIDING.

Just in case you do want to install a new petcock, Pingel makes one though it is expensive. When mine go bad, I just buy a new one, less heart ache. Rebuilding one is a waste of time and money. The big issue in replacing this petcock with anything else but a stock one is the clearance between the petcock and the air box. You'll notice there ain't alot of room right there.

check my last post again, did some major editing when I realized what you said.
 
Screenshot_2016-02-01-15-18-15.jpg the fuel is coming from the breather tube (11) it's blowing my mind. It runs like a top even while pouring fuel into the air box. I had one guy tell me he had a similar issue and that the pet cock was bad and fixed the problem. I just don't want to throw parts at it. I havn't had it on the road yet lol, going to get it out this spring.

Can't be, there is no fuel what so ever that even gets near the breather tube. All it does is vent the crank case fumes (cheap pcv) back through the air box, nothing else.
Make sure the tube goes from the top of the valve cover to the air box. Something is way wrong here.
