    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.

I have a 1978 gs 750 that the top end needs to be re done, but funds are low right now and I have the opportunity to pick up a good engine but it's out of a 1983. Does anyone know if the swap would be a bolt in?
 
Not really , the engine to look for is a '78 - '79 GS 1000 engine. Bolts right in, is lighter and physically smaller in every dimension than the 750 engine, it's what Suzuki should have done in the first place. We are doing another on a friend's '76 750 this next weekend, good stuff.
 
Thanks for the info. Got my hands on a 1000, do you have any other things I should look out for to make the swap a bit easier? (carbs, jetting etc.)
 
Jetting depends on the configuration of intake and exhaust. Do you have the 1000 carbs? IIRC they are larger than the 750 carbs.
Tom, won't he have to fabricate the rear motor mount, or mod it?
 
He will need to modify one of the front top engine mounts and since he already has the right carbs, re-jet them to 1000 specs. ;)
The right foot-peg mount will also need to be modified a little.
 
So the 750 carbs re jetted will work? I also only have the 750 exhaust, will they bolt up or should I start looking for something else?
