    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.

Before I see about ordering shims from Z1enterprises, just wondering if anyone has two 2.55 shims they would part with for my nephew's '83 650G, as we are in the middle of a valve adjustment??
Can be mailed regular 1st class 44 cent stamp envelope to me. I have a 2.70 and 2.75 for trade. Please let me know tonight.
thanks

We had some difficulty getting 4 of the 17 valve cover bolts off the 650G. Felt like they were torqued down way too much or just corroded from too many years of not being touched. Anyway, after soaking with PB blaster 3 came free but even after being careful, one did snap. After removing the valve cover we found that there was about a 1/4 inch of the bolt sticking out from the head. More soaking and attempts with locking pliers did not pry it loose. Next I'm going to heat the bolt with a propane torch and see if the crud bond breaks free.
My next thought would be to spot weld about 1 inch of a threaded bolt on with it's head dremmeled off, then guide the cover back on, use a nut along with the other 16 bolts and gently tighten it all down. Since little torque is required I thought this might be a safe way to proceed without creating a major project. I hesitate to use a drill and ez out, but since it is an inner bolt I can't get at it because of the frame anyway.
Any thoughts?
 
Hopefully the heat from the propane will do the trick. Had the same problem on my son's 550L, and used a heat gun on the alum, along with liberal amounts (and patience) of PB Blaster. It broke free & finally threaded out.

I chased all the threads with a tap & of course always use anti-seize on everything now.

good luck
