How do I make GSX-R slingshot carbs fit?

I've seen these flatslides on KZ's before, but I held a set up to a motor in the shop where I used to work, and the spacing is off between the runners and the carbs. What do I need to get these on my bike?

Offset intake boots? From what bike?

Custom boots? From where?

Just looking for someone that has done it to point me in the right direction.

Thanks

Don't have any experience with those carbs but some of the flatslides are mounted on a bar so that the carb bodies can be loosened up and the spacing adjusted to fit different motors. Have you checked that option yet? Otherwise, those other carbs may have been another model of carbs. I know there are some that do fit but not sure if all models do or can be made to fit!

I rec. calling the folks at Schnitz Racing.. (that's where I got intake man's to fit my GSXR "slingshots" to my GS1100) Spacing may be an issue, But someone there will probly know. G

Get yourself a set of brand new boots that are the right size. New so that the rubber is still nice and soft. If i remember right, they are just a tad off on spacing and they can be squeezed on if you put a little muscle into it

They don't have and slots for the carbs to slide on the rack.

The difference between the carbs and ports is about half the diameter of the boot on 1 and 4, with only minor issues on 2 and 3.

My current boots are new, but it seems that the flatslides will need larger boots, say BS34 size.

r u sure they are off a Suzuki ? gsxr's should have the same spacing but Honda flats are a dif spacing.b u said bs34 ,are the vacuum slides?

Hello, i would like to ask you and everyone: could you installed the GSXR carburetor ?
I have a KZ1000 J model '81 and i want to buid up '89 GSXR 36 carbs. What bike intake manifolds fitting ? Unfortunately, my English is not good My german and my hongarian better :laugh:
Thanks: Richard / Budapest

the intake manifolds on the J will fit a 36mm carb. but u must make sure the carb spacing on the gsxr carbs is the same as the kz. some models r some r not. the GS carbs had the same spaceing as the KZ.

Hi Guys

I fitted the BST36SS Mikuni Flatslide Vacuum Carbs to my KZ1000 Head, with the standard rubbers. But, I had to reduce the intake of the carbs with a custom aluminium reducer to fit the rubbers. The spacing works out great. I did however built a aluminium air-box to fit only one K&N type filter. Is there any issues using vacuum carbs on this motor?

There is no problem with vacuum carbs. I think the problem may lie in getting them to work properly with intake restrictors.

By the way, nobody has posted to this thread since 2012, and I have not seen any of these folks post in quite a while, so you should not expect responses from them.

To make the GSXR flat slides (1985/1986) fit the 650-1100 KZ you need to take the apart and fabricate a new choke rod, throttle rod, and upper/lower link bars. It is a bit of work. Here is my street bike with a set fitted to a modified air box.

 

The carbs are almost identical to the new TM series flat slides so a lot of the parts are the same. The only issue is trying to get a hold of a good used set, the prices on these have skyrocketed in the past few years.
