    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.

Gas leak again

I have a 1983 GS 450 GA (yes an automatic) It has been running great. It developed a good leak from the air box. Only when the engine is off. AHHHA I said float sticks. I pulled the carbs. cleanned the nedale valve and tried to adjust the floats. Things were fine for about a week. Then I get another leak. This time from the right (I think that means #2) carb drain. Before I go back in. Is this flaot again? Also what is causing this repeat problem. Shloud I install an in line fuel filter? Oh, the Petcock is new OEM part.
 
If it does it while the engine is off, the petcock isn't shutting off like it should. That said, you also have a float that's sticking a bit open, allowing the leak, it doesn't need to leak much if the petcock is flowing, and the engine is off, and may not be a real problem if the petcock were working. Install a fuel filter, there may be a particle that's causing the needle not to seat right, causing the leak.
Also check your oil, sometimes gas will leak into the cylenders as well as the airbox, and get into the oil. Gas in your oil is bad, and should be changed asap.

Good luck.
 
FLoat valve is leaking, When you clean it make sure to replace the O ring
& check the oil
 
yeah. the leak happens only running. so I'm thinking needle is not seating. cause grud from old 1983 fuel system. clean needle vale seat again. I will try to find the O ring. Instal a fuel filter to give a long term fix. the inside of the tank looks OK. do we all agree or am missing something?

You just put in a new petcock, right? So you remember that it had a screen on it? That screen should be all the filter you need. I installed an inline filter on my 450 and it gave me fuel starvation problems. :x
