    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.

Clean Up Head

I'm replacing the head on my 750, and I'd like to clean it up before I put it on the bike. Could I "sandblast" it with something? I was told you could use fine silica on aluminum, but I dunno. What about walnut shells, plastic beads, etc? Anybody have any experience in this area?

Get it glass bead blasted...
 
I sand blasted a GS550 head years ago. I used cardboard and duct tape to cover the cam area, combustion chambers, intake and exhaust ports. I then used the lowest pressure possible to get the finish I desired, being careful not to blow through the tape or get under the cardboard. A very careful cleanup and my head was looking great. The blaster was filled with very fine sand, I don't remember the grit.
 
Someone here posted about blasting with baking soda. The pics they posted looked good. It made sense and the residue left behind is water soluble.
