    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.

That's one way. Another is to check the valve clearances; if the clearance is big that means the valve is not seating.
 
Well I think everything is going much better. I am now checking the valve clearance. I want to make sure I am using the right measurement for the clearance can you tell me what is the right spec for 1981 gs550l? I am not trusting what I read in the manuals since I got the timing wrong.
 
I got it started

I got it started

The bike started up Yay!! I checked the compression and it is at about 105. Kinda low. My battery was running low so I have to charge it and check it again. All the cylinders read very close to the same reading

The manual is fine, only you have to use the right one! Proper spec is .03mm - .08mm. Use the service manual guide on how to position the cams when judging clearance. Don't just point the lobe away from the bucket, position the cams per the manuals instruction.

Oh, and since you have new rings it's advised to take the bike out and ride it aggressively. Don't baby it. The rings need pressure into the cylinder walls in order to seat properly. No need for a top speed run or anything, just ride it around town good and aggressively and use lots of throttle
