    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...

    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.

Tire and swing arm

I have a 76 GS 750, What is the widest tire I can put on the stock rim and in the swing arm? Also what would I have to do to run a modern sport bike tire and rim? Also can anyone point me in the direction for an extended swingarm?
 
120/90-18
Fit a 1100 E swing arm and modern wheels
No idea
 
You'd need an 1100E swingarm with a conversion bush for the swingarm bearings. A 4.5" Katana wheel with a GS550 Sprocket drive hub & an offset front sprocket. 530 chain conversion. You'll also need to modify the brake tie arm.

A 160 tire is the biggest without even more modifications but it can be done. How much money & time do you want to spend & how good an engineer are you? :)

Here's a 750 SPecial I built a few years ago from an 83 model. This was running a 170 on a 5.5" wheel.

A wider tire is mostly for looks. Modern tires are far superior to what was available "back in the day", so the 120 that Big T suggested will work quite well.

As others have noted, if you really do want to go wider, you will at least need to change the wheel, and the swingarm is also a good upgrade.
