    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

I had this exact same problem today (albeit on my GS400.) I took my cylinder head off and was able to crank by hand about half a full turn before it would get stuck. I shall now check for the cam chain bounding around the bottom sprocket. Just to reiterate the above advice; I should be able to hold the cam chain up with one hand (creating a tension) hopefully freeing the potentially bound chain and be able to crank a full revolution by hand?

Yes. You may even be able to turn the engine over by pulling on the chain itself.

Before you put it back together, please consider changing the base gasket, as well.

When you pulled the head off the top, you probably also jiggled the cylinder block, which will disturb the baske gasket, likely tearing it.
It would be a shame to get it all back together only to find that the base gasket leaks and you have to do it again. :o
