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 am doing the valves on my GR650. I left the valve cover off and had a oily rag on top of the case. Then I noticed some rust appearing on the cam lobes. It looks like it will mostly wipe off, and I have now put the valve cover back on as the bike is in an unheated garage for the winter.

Will this stuff come off? Have I caused permanent damage?

Appreciate your help.

Does it just look rusty and not rough to your fingers if you run them over it?

If so, it'll be like my camshafts were and the lobes got like that. I just oiled them, reassembled, and good to go.

I'd only worry if it is really starting to roughen the surface and corrode a lot.

Mine sat out of the motor for probably 5 or 6 years like that...
 
Use some Scotch Bright and WD-40. Rinse ,repeat .You'll be fine.
 
Steel wool +oil. Its only surface rust. I've had many parts do this. Its flash rusting. That can be reversed !

To do it right. Take the cams out and do the cleaning to keep everything out of the engine. Then reassemble with lots of oil covering everything.

Thank you for posting this as I noticed my cams doing the same thing. I forgot to try to clean them today but will do it this week.
 
I'd keep steel wool and scotchbrite away from the engine. That stuff is abrasive and loose particles will fall into the engine unless you are very careful.

If the rust won't wipe away I'd pull the cams or just leave it alone. And oil the cams and all the valve train parts with lots of oil.
 
Thank You

+1 here, I would pull the cams, and clean them, even a light rusting can play havoc with the surface hardening, so don't hang about.
