    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.

1992 GSXR 1100 Carbs... Will they fit an 83 GS750E?

I'm wondering if '92 GSXR 1100 carbs will fit on an '83 GS750E? If so, has anyone re-jetted them, or have any suggestions on jetting for a GS750E? The GSXR carbs seem to be cheap on EBAY so I'm wondering if they are worth giving a try

I know they swap on the 1100s. Since 1100s have 34mm and 750s have 32mm I'd have to say no.
 
What size are the carbs? 34's will be alright but bigger than that and you won't get them on the manifolds.
 
I'm looking at a 92 GSX-R1100 service manual and they say the carbs are BST36SS with a 36mm bore.

I assume the bore is the inside diameter of the intake/engine side?

That would be correct. The inlet side is more like 54mm. You could get manifolds from an earlier GS1100 that used 34mm carbs. The 36mm carbs shouldn't flow any more air than my 34mm RS flatslides so tuning should be doable.
