Ghosting, I believe it's called. Or "Ghost-posting". I didn't know what this was until recently, because I'm a baby boomer. ha!

Golly, I hope I'm not the cause for y'all's vitriol...I was slow to respond too, until i changed the setting for email notifications.

It's quite easy, there is a lot of info out there, but I'll summarize...
First, you will be using your 91 swingarm axle (the one that attaches to the frame) and the bushings and spacers from your `91, amazingly the bushings from the 91 slide perfectly into the 94-95 bushings. You can cold weld them or use loctite (what I did) I think I used the same spacers as well from the `91. You will need the rear brake stay, and caliper from a Water cooled gsxr, I think some bandit stuff crosses over as well. I did this conversion all on info I've picked up on various forums. I bought the rear wheel from a 95 as well, you will have issues with alignment with the earlier wheels. The bonus is the 94-95 wheels (straight spokes) are lighter as well. There are quite a few parts from the 94-95 needed to make this work. I started with a bare frame and no donor bike, so I was going to need all this stuff anyway. The dog bones from the 91-92 won't work, you'll have to use 94-95's. You can reuse your stock shock without any problems. Although the ride height sure looked low. I fitted an oem unit from an `06 gsxr1000. It is a little longer, which is ideal if you like going around corners. When we were racing these things, they had to be jacked up a bit in the rear. I did a bit of grinding on my upper shock mount, and had to space out the mount from the frame a bit, still a work in progress.
I had a slew of different pivots I tried, I think I settled on the 91 pivot with dog bones from the 94-95.
if you are using a bmw s1000 shock, it won't work, the reservoir hits the swingarm bracing. the `06 unit points the reservoir higher and it clears. If you use your stock shock with a remote reservoir or the proper aftermarket one (which I can't find for under 500 usd in the US), you can run the stock battery box, I had mine fitted, until I decided to make the later model shock fit.

The BMW shock reservoir won't clear the braced swingarm. This is an `06 gsxr1000 shock. Seems under sprung. Sorry to the original poster for the thread jack.

Do you have a picture?
Took me awhile, sorry. I used washers to get it to fit. I won't ride it like that of course. looks like I will need a spacer. about 5-6mm thick.

At the moment, no. I put the stock `91 shock back on. it seems to need a spacer/wedge that would move the upper mount rearward a bit to make it work.

One of the best rear shock is Ohlins SU503. This shock is for the GSXR 1000 K5/K6. I have used this shock for all my race builds GSXR 750 -88, GSXR 1100 -90 with GSXR 750 -95 swingarm, including a GSXR 750 RR.
I need to ask? How? I have a `91 750, with a `95 arm. I bought an `06 1000 shock and it won't fit. Seems the upper mount just doesnt line up.

@xracerfranzI usually 1100 N frames and use 750 N swingers and 750 or 1100 shocks. Never had an issue with the bottom shock mount to link area. Your braced swinger is a bit different though. Hopefully one of these links will line up.
Thanks. The 93 and 94 pivots were a bit short, the 91 was a little longer. I can't help but think a spacer on the top shock mount to frame interface might solve the clearance issues. I just don't want to screw up the handling...
-
Well, from what I see, if you have an 1100 frame the swap my be better, although the swingarm is two inches shorter!
-
Something I noticed when looking at someones 1100 build (of the same year) is the upper shock mount is part of the frame, and seems to put the shock in a more vertical position. I want to be careful and not screw up the handling on this bike. I had a bmw s1000 shock which is considered a drop in mod for `91's, but since I used the braced arm from the `94, it buggered that idea. The reservoir on the shock hit the swingarm. I will have to use dogbones from a `94-95 as the ones from the 91 don't fit.
Ugh. So much hassle just because I wanted a braced arm. I've never done much the easy way...

@xracerfranzI have 2 1100 lower links that I can measure for you. If they'll work we'll figure something out. I'll snap a pic with measurements when I get home this afternoon.
Thanks! It's tricky since I used the braced `94 arm with the `91 frame...

.... for the front end swap you can use the “ all balls racing” website fork swap guide.....
I ended up finding a `94 750 frontend, the blue one and decided that would be the way to go. It would probably qualify as the best that came on gsxr's up until `94-`95.
Maybe i'll upgrade down the road. this was an easy fit, using the `91 lower tree.

Link to the frame ears or shock to link, or link to swingarm?
Bottom link to lower shock mount. I had another answer from a member that recommended shaving some material from the top shock mount to allow some movement. I'm beginning to think i may just get a stock shock to use in the interim until I find a nice aftermarket unit in the future. There was no donor bike in this build.

Oh, specifically, it doesn't seem the the link to bottom mount is going to work.

Hey y'all , just in case someone is following, I've put a `94 750 swingarm on the bike , but I'm having issues getting the shock to fit. I'm using an 06 gsxr 1000 shock, having heard and read it's a direct bolt on... I've tried several different pivot links, and it seems I should be using the M, or `91 link.
Any insights?

Thanks guys!
Good points all round

Hey Y'all!
Greetings from Georgia, USA!
So, I've had a very clean 91 gsxr750 frame and 93 swing arm hanging around the garage for awhile and I have been plotting to build a tire smoking wheelie machine for fun. My first race bike back in `90 was a gsxr1100K, so there is some sentimental value here. I found a used bandit 1200 motor on E bay and just picked it up today from the freight terminal.
Very excited.
I've been trying to find a comprehensive parts interchangeability guide, which I swear I've seen here before. I'd like to put a newer lighter, radial braked frontend on it, plus newer, lighter wheels. I like the late 2000's stuff, but I need some specs.
Any help from you lovely people would be helpful.
