    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.

1979 GS750E valve clearances

They are (in millimeters) .03 to .08. Anywhere in that range is acceptable. Truth be told, you can even go on the loose side when changing your shims, say the clearance is .04 or .05, throw the next size up in there, taking your clearance to .09 or .10 Its ok to be a little loose, as they TIGHTEN with age. I would not recommend going any looser than say .12 for risk of floating a shim out of the bucket at high RPM.
 
Would these numbers hold for the 79 GS750L? I am guessing it's the same engine.
 
I would have preferred answer with a simple "thanks" to show my appreciation for providing me with this information, however the forum only allows for a minimum ten character post.

Re-reading this, it occured to me i may have been a bit confusing...

Say your measurement is .04. Acceptable, but soon enough you're going to have to change it. If the current shim size is a 2.70, you could put a 2.65 (actually SMALL not UP) and take it to a end clearance of .09mm...hope that clears it up a bit.. .
