    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.

Hi all,
I have been having some trouble with my GS450E lately. It was working fine (not perfect, but good enough for everyday use) and then one day it developed this problem: it will only run with the choke all the way open, during which time it idles anywhere between 3,000 and 5,000 rpm. If I start to close the choke or give it any throttle the engine dies. A couple days after this started happening I changed the oil, because it was time to anyways, and after doing so I noticed oil leaking from the head gasket (I'm fairly sure it is the head gasket). Maybe it was leaking before I changed the oil, but I probably would have noticed. Until I noticed the oil leak my plan was just to take of the carbs and completely clean them out. What would you guys say to do? Thanks.
 
You can try re-torqueing the head with a torque-wrench, but cross your fingers it works and don't overdo it. Follow the shop manual's procedure.
a leaky head gasket is too obvious to ignore.
The choke is not a choke really.There's no butterfly valve closing... It's an enricher that draws its gas from the carb bowl with the engine's vacuum. Given that your engine sucks well enough to do that, it indicates you have some compression. You didn't mention smoke from exhaust so I assume it doesn't. You may have an air leak at carb manifold rubber collars. or several other issues inside the carb.
go here and look for what you need. There's a lot of great stuff.
