    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.

Just bought a GS450s for my wife to ride, and just picked it up this weekend. The funny part is I forgot to get the key... (doh!) and will go over and get the key on Tuesday.

I was told that the bike will start and run, but it cuts's out after a minute of running, the guy suspected that it might need a carb re-build. I have re-built carbs for my Yamaha XZ550 more times than I care to remember. Any suggestioins or tips for someone new to these carbs? and, would anything else be causing this cut-off?
 
The carb's are fairly simple,also check the fuel tap is working correctly,clean the fuel filter it's on the tap inside the tank.
Check the breather on the fuel cap.
Give it a good tune & service.
 
Thanks for the reply, I have not even really looked too much at the bike yet, I am going off of what someone else said. Sounded to me more like a fuel flow into the carb problem. I have not taken the tank off yet (no key yet...) to check out any type of fuel pump.
 
Thank you, that will help. gravity system. I do not think the bike has very much gas in it, and that may be the problem. Was told that when the bike is running, it runs great.
 
you might wanna take the carbs off anyways (its sooooo easy, especially compared to the v45 sabre 8O ). On my GS400, the little screens that let fuel into the float bowls were plugged up, and I had major problems. At any rate, add a good MOTORCYCLE fuel filter inline to keep those things clean once you're done
