    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.

Aluminum Swingarm Conversion

What's going to be the easiest way to drill my frame out for the conversion?
 
There was a lot of discussion on this a while back... plenty of info in the archives if you can find it :)

Some did it by hand, others reamed it, others made adapters, others made a new plate & welded it etc etc.
 
I just went crazy, drilled the frame out and got lucky. But I reckon the safest way (without high tech gear) is to tap the holes to 16mm and then ream. This will give you a better chance to keep it all aligned.
 
I just drilled the frame out to the 20mm swingarm bolt that I needed to use the Bandit swingarm.
I am a human drill press :D No all kidding aside It is not hard to get it straight when it has a pilot hole already.
I wanted to use the larger bolt for the extra strength

Sounds like a winner for me! Thanks for all the ideas. Got tired of reading all the threads about the swap. Thanks again!

BTW the 16mm hole will take the 1100E swinger pivot bolt, and that bolt is longer than the stock 750. You will need spacers or cut about 1" of new thread. The swinger is also a bit longer so you will need a couple of extra chain links, so.....this is a good time to convert to 530 chain & sprockets!
(If you do, don't forget to account for the longer swinger when calculating the number of new chain links.) I didn't:o
 
Broke my tap 3/4 of the way through but got it done. Took a new 120 Link 530 chain. Anyone doing a 1979 750 using an 83 GS1100 Swingarm the bolt does not need to be cut down shorter.
