36mm round slide carbs off of a 750 oil cooled Katana, on a 1100E ?

I think they are possibly VM carbs, they are stock on a mid 90's oil cooled Katana. Has anyone used these on an 1100E, do they fit.
 
Hi, never fitted oil cooled kat carbs on a gs1100, but the fitment of mikuni rs36-d3-k lists 88-92 gsx katana 750 and gs1100 plus many more bikes.
 
From what I read it looks like they would fit. I guess I would be on my own on the jetting. I was thinking someone here would have an idea of what jets to use with oval K&N pods and a header. One of my projects is an 81 1100e with an 82 1100E engine with a 75mm bore. I thought the carbs would be a good small bump in flow for the increased compression and displacement.
 
Are you sure they're not BST 36mm sling-shots?

Thought I've seen Kat carbs from the 90's on Ebay in this configuration, but with metal caps or various different choke knob set ups.
 
The steel top "tin top" carbs are from early gsxr 11's and the gsx1100f's are 34mm. Side pull chokes are gsxr carbs, cable pulls are from teapots and powerscreens (u.s. katanas) carb spacing is the same. If they fit in the spigots they work.
 
I found the spec in the manual BST36SS, it came with an extra rack of carbs too so I have a lot of pieces to work with. someone had been into the engine I believe, so the story goes. I did ride it and it impressed me as far as power, it has a six speed if I remember correctly. There is a small dot cast on the side of the head. Someone point that out to me once and said something about a slingshot head.

They'll fit, but the dual K&N's will be needed I believe, as the back of carbs are sort of oval shaped, so I don't think "cone" K&N's will work.

Float height can be fussy, I had to lean mine out a bit more than 14.6mm. The emulsion tubes wear out easily & create a rich condition.

I'm running a Factory jet kit with 4 times replaced emulsion tubes, think they're about $100 a set.

The shorter throttle cable from a GSXR, mine was a 1990 model can be fitted into the stock handlebar housing, the stock one is too long.

If you do run them put the cable on the carbs first & snake thru frame to handlebar, it's really hard to get the cable on the carbs on the bike!

I just picked up a used stock 1150 motor & the carbs work + the spacing is the same for a 1100.

Currently running 135 Mikuni mains, but have a bit of fluff to figure out at 3k which is probably more a needle/pilot jet issue.
