    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.

Have a ported stock valve gs 1100e head going on a 1260 engine I'm building. Prob use 370 lift webs
11to1 comp 36-38 rs flats old style v&h pro pipe. Going to install oversized intakes and update valve job for 28.5 ss intake valves. How much more improvement if I do oversized exhaust valves. Would it really be worth it Just trying to budget. And already have the intakes will be a street strip bike 6 over cal fab old model swingarm 5.5 inch gsxr wheel with 180
tire in an 1983 gs1100 ES.
 
You also need bronze guides with cams that big. The stock guides are too tall & the retainers will hit the tops of the guides at full lift. You should also go to 24mm exhaust valves.
