    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.

Has any one installed newer GSXR Carbs on a older GS1100? I have a chance to buy a set of 1993 GSXR 1100 carbs. I was wondering if there would be any significant gains over my stock setup which is a 1980 GS 1100 16 valve ,4 into 1 header. Thanks Joe
 
93 GSXR 1100 may be to big, IIRC in 93 they were 40mm, I suggest you check this out.
If they are 38mm they will go straight on, you will need a different throttle assembly though, as they run a push pull cable.
Flatslide carbs will make a difference to throttle response, and should add a little top-end power.

Carbs

Carbs

93 & up are watercooled gsxr's the spacing will not work. You will need 86-92 oilcooled carbs. 86-88 gsxr 1100 are 34mm, 89-92 1100 36mm U.S models, 88-89 750 36mm, 90-92 38mm 750. You can use your stock throttle cable with factory gsxr carbs the aftermarket mikuni RS flatslide carbs use a push/pull throttle cable set up. They are a good upgarde for the 1100's if your using aftermarket exhaust and individual filters. The 36mm carbs will work and are easier to come by than the 86-88 34mm 1100 carbs. The 87 gsxr 750 also upgraded to the 34mm from 31mm in 86. Hope this helps.

I haD A set of 1986 GSXR 750 carbs on my 1980 GS1100, ran well.\
I am sure others might work better for drag racing or whatever, but those worked well for my general floggin habits.

I recently chatted with my buddy who has been building perf Suzis and Kawis for the last 25 years about the same topic. He very firmly suggested that if I wanted no tuning problems I need to go with 36 or 38 mikuni rs flatslides and stay away from the gsxr carbs. He said I'd constantly be chasing flat spots around with the GSXR carbs.
He has tried it all, broke it all, raced it all, and the busy shop with trophies to prove it.
His shop's bike has a fastest time of 6.26 @ 226mph in the quarter.Its 13 feet long and has a 13 or 14 inch rear car slick.
