    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...

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 have just bought a 1980 gs1000g that is in pieces. The engine is out but in one piece however the rocker cover was taken off for a while and the result was 4 cam lobes have rust on them with some pitting. I cleaned up some of the rust but not sure what to do about the light pitting.
Can anyone please help me with ideas about cleaning the rust and whether I should be concerned about light pitting. Thanks

The shim and bucket GS valve train is bullet proof. I wouldn't worry too much although the cams are very durable so you should be able to find a decent set of used cams easily enough if you are nervous. If you get stuck drop me a PM since I have an extra sets you can have for cheap (other than the shipping cost).
 
Thanks for the replies so quickly.
I am glad you guys have the expertise!
I am not an expert mechanically but when the cams are not activating the valves does the back of the cam still touch the shim?

Also Nessism I had a look at the photos of the bikes in your list and they are unbelievable I cant believe the detail well done They must have taken some serious hours to complete.
Did you pwdercoat the frame on the gs1000s and what was the condition of the bike to start with?
Thanks for the help.

No, the back of the cam lobes and the shims aren't touching when properly adjusted. This is the "valve clearance" that has been discussed ad nauseum on this site.

If you really are intent on reassmbling this bike, you absolutely need a shop manual for it.
