    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.

  • In order to help others find info on a particular bike, be sure to put the year, make or model of bike that you are asking a question about, in the Topic Title. This will allow people to pass by posts they have no interest in.

Did I hone too much?

I don't know about honing too much, but it does seem like your hatch pattern is off. It should look like this <> but standing up. Either your drill was spinning too fast or you weren't moving it in and out of the cylinder fast enough. That can cause rings to not seat properly. Also, once an engine is honed (at least when it comes to cars) you're supposed to load the engine (about 3k rpm steady) for a few minutes, then drain oil immediately. Don't quote me on those values as they differ from application to application. You do that for proper ring seating as well.
 
I used 50 grit emery cloth to smooth out casting flaws, it is actually rougher than before.
I have a 1990 GSXR 750 head here as well and it HAS BIGGER PORTS than this one had and has, go figure.
Anyway I did it and it is done no going back so can we drop it?
I was thinking of using my spare cylinders and pistons until I found the imperfections on the cylinder wall of one hole, so I think I am just going to decarbonize it and put the head back on and just run it.
