    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.

2005 GS500 Carbs on 1980 GS450

Just bought a 1980 GS450, 15000 miles, been sitting for 4+ years. Got it home, and the carbs were frozen solid. I found a set of GS500 Carbs, 34mm Mikuni and bolted them on, bike idles and starts nicely, but runs pretty rich (as expected) any ideas on what would be the first changes to make to the jets, needle, mixture screw, etc. and what part numbers? I really can't wait to get this thing on the road. My first bike was a 2001 GS500.

OR if anyone has a good CHEAP set of stock carbs, I will trade or purchase.

Thanks!

I have a nice set of 81 450 carbs you might be interested in. Bike was running great before it was wrecked three weeks ago. Please let me know.

It would probably be significantly easier to clean the 450 carbs than to get the 500 carbs to work at all RPM ranges. You could drive yourself crazy with trial-and-error jet replacement. If you've got a whole lot of main jets of different sizes, I'd first try those. If not, just clean the 450 carbs.
