    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.

smoke from exhaust pipe???

Hello, this is my first post on GS and i love the site. I have a 1980 gs450l with stock exhaust. I am in the process of getting the bike up and running. The exhaust pipe on the left side smokes very little after running it for a couple minuets. It is a very fine smoke, white in color and what gets me is that it smokes where the pipe starts to run parallel with the bike (directly underneath the gear box and gear shifter). There is a fine smoke that comes out before it can even reach the muffler. There are no holes in the muffler to let the smoke escape. I am absulutly stumped and could use any and all advice and suggestions. Has this happened to anyone before?
Thanks,

John
 
this may sound odd but what does it smell like (odorless sour sweet etc)
 
Check for a drain hole in the exhaust. Suzuki put them in to let condensation get out - at least my 550 has them.
 
Check for oil leaks around your oil pan... sounds like oil is dripping onto the exhaust and burning off smoke after the exhaust gets hot.
 
Maybe it's 'ghost smoke'. You know, the magic kind that can move through the wall of the exhaust pipe.

*ooooooooooooo* (scary ghost noise)

Howdy John.....That's most likely, steam from condensation in, or around, the exhaust at that point. You mentioned left.......and with the bike leaning on the side stand, this is the side condensate will more likely collect.
