Updated Parts Interchange: 88-92 750 and 89-92 1100

If you have something to add post a reply and I will add it to the List. I know with a lttle work ANYTHING can be adapted but this is more for the Direct swaps.

Forks:
all 92-93 600, 88-95 750 and 89-98 1100 use the same bearings so the triples are a bolt on but the 92-93 600 and 93< 750 and 1100 have different steering stops so you have to work with that.
Late model forks work using the steering stem out of your triples and making a sleave for the late upper triple.

Swingarms:
all swingarms from 92-93 600's, 88-93 750's and 89-93 1100 have the same bearing size so are a direct swap. the 94-95 750 and 94-98 1100 arms work but you need to slip the bearing sleave and spacer out of your swingarm and replace the ones in the later arm.

Wheels:
All wheels interchange but you need the correct carrier.
92-93 600, 88-93 750 and 89-93 1100 are "twisted" spokes in 3.5 front and 5.5 rear but the 88-89 750 has a 4.5 rear.
94-95 750 and 94-98 1100 use the "straight" spoke wheels and these are lighter then the "twisted" spokes

Engines:
All swap. Air/Oil is Air /Oil be it 600, 750 or 1200 Bandit, 600, 750 or 1100 Katana, or 750 or 1100 GSXR.

Oil coolers:
"curved" (91-92 750/1100) coolers have the mounts in the same spots but the frame's lower mounts stick out from the frame farther on the 91-92 750/1100 but you can cut and space them out on your 88-90 750 and 89-90 1100. You need to get the hoses for the bike the cooler came from or even better swam to Earls UK fittings and braided lines.

Heads:
all can be swaped but cams are different and tooth count on the cma sprockes is different on the 88-89 750 and 750 Katana heads. Valve sizes are smaller on the 750 (except the 88-89 750) and there may be other differences.

Frames:
All swap but there are some differences in the rear subframe for the 91-92 750/1100 and the 1100 frame is 7lbs heaver then the 750.

Shocks:
All 92-93 600, 88-95 750 and 89-98 1100 shocks swap but the spring rates differ and the hose length varies.

Bodywork:
All lowers are the same from 88-92 750 and 89-92 1100
All the tanks from 88-92 750 and 89-92 1100 swap but te 1100 has a fuel level sender in the bottom rear so is slightly smaller in cap.
Mids from all 88-92 750 interchange
Mids from all 88-92 1100's interchange
Uppers from all 88-92 750 interchange but you need to use the correct mount 88-90 or 91-92.
Uppers from all 88-92 1100 interchange but you need to use the correct mount 88-90 or 91-92.
Uppers and mids can be swapped from 750 to 1100 but the holes in the mids will not line up and you still need the correct mount 88-90 or 91-92, the bars also have clearance issues.

Here's a chart for wheel swaps.........

Re: Parts Interchange 88-92 750 and 89-92 1100

IIRC the '89-89 750 head is larger than the 90-91 750 head. The 90-91 head is the same size as the 86-87 head and will not fit the 1127 motors. The 89-90 head will interchange with the 1127. The katana 750 head will work with the 88-89 750 or 1127 also. The bandit 600 head is dimensionally similar to the 86-87 or 91-92 gsxr750 head, but the cam sprocket/guide is different.

what about coils from these 750s? dont they interchange with newer bikes from 2000+?
NO.

The ignition-coils from the oilers *will* interchange with the coils from the first-gen water-cooled gixxers, GSX-F katanas, Bandits, and RF600/RF900 - but starting with the SRAD's, Suzuki started using individual coils on each spark-plug and this cannot be directly-swapped-out for the two-coil setup from the earlier models.

does a 1993 gsxr 1100 subframe fit onto a gsxr600 frame???
how close are they?
Yes it does but the 1100 has a "grab rail" while the 600 uses a strap.

Now I just swapped a CIP (Coil in Cap) from a late GSXR to my DRZ but the only trouble is that you need the plug from the wiring harness that fits teh coil and it is not seperate, it is part of the harness so you have to destroy the harness to swap.
I am finding that Suzuki did the same thing on other bikes that they did to ours (Parts swap easy) by putting RM USD forks on my DRZ.

Your best bet for interchange would be 92-93 600, 93-95 750 and 93-98 1100's as they are the third gen models and many parts interchange.

Does anyone know if it's possible to do a 6-speed conversion on a 1990 GSXR 1100? The 5-speed just kills me on long freeway hauls.
Taken from oldskoolsuzuki.info

4. 750R 6 box in a 1127 motor
The only hard thing here is to have a hole drilled through the gear box shaft, for the pushrod.
The 750 6 boxes have a single row bearing on the output shaft, and the clutch does
not have a diaphragm spring. So the easiest 1127 engines to put a 6 box in are the ones with a
single row bearing on the output shaft, and no diaphragm clutch, ie. only the GSXF1127 engines.
In these engines the 6 box drops straight in, only the shaft has to be drilled.
Second easy would be an 1127R engine with a diaphragm clutch, but no double row bearing (88-90).
In this case the box would still drop in, but for the clutch one would have to use the inner
clutch parts from a GSXF1127 (with normal springs) and the outer clutch basket from the 1127R
(with a straight cut gear, not helical).
Most work is in a 91/92 1127R where one would have to match the clutch as above + find a
solution for the double row bearing (the solution is actually to turn the double row bearing
inside out, and make a little hole for the small pin).
Of course the shift drum and forks from the 6 box have to be used as well, but they drop in
any 1127 without problems.

Re: Parts Interchange 88-92 750 and 89-92 1100

Great list!!!!

Note on the wheels:

92-93 GSXR600 are "straight” spoke and the rear is unique to the 92-93 600.
750/1100 "straight” spoke rear looks the same but are slightly heavier (Bigger cush cast into it).

Since the “straight” spoke wheels are lighter than the “twisted” spoke, and the 600 “straight” rear is lighter than similar looking 750/1100 it's the one you want if you are looking to swap.

Since it only came on the 600 for two years it’s also the most rare. As you noted, I believe you can swap with the 750/1100 if you use the matching cush assembly and maybe a bearing swap.

If anyone is looking, I have a 92-93 GSXR600 wheelset w/rotors and tires for sale on my website @: http://lwsuperbike.20m.com/photo.html

Was keeping them for a project that appears is never going to happen.

Side note: The 92-93 600 rear is also a fairly easy swap into a SV650 to get a 5.5” wheel as I’ve done several.

Re: Parts Interchange 88-92 750 and 89-92 1100

ok, Does anyone know if the header pipes from either the GSF 600/1200 bandit, fit onto a gsxr 750 1989 J??? I know they did the GSF750 bandit in japan, but finding one of these in breakers in the uk, is like trying to find a contact lense in a swimming pool...
Also, the bike is an import (eeyuck) from itally (we think) so has KPH clocks. this isnt too much of a hassle, but is there a rescrictor on the bike/ignition?? and finally, from a bandit 600, would the igniton advance thingy fit onto the 750? more over would it work or blow the lump???
need help with these urgent, bikes running like a sack of spuds.. the exhaust is well, cant type how we feel about it(laser road horrid thingy) pipes seem too small.
Many thanks...

""all 92-93 600, 88-95 750 and 89-98 1100 use the same bearings so the triples are a bolt on ""

Hey Bones, Are you telling me I can put a steering stem and bearings from a 89 750, into my TL 1000 front end (trees) and bolt it onto my 93 600 frame with no mods ??????
This is important, I do not want to use the adapter bearings we discussed so long ago, and to this day I havent been able to dig up a steering stem from a 93 600 either.
Thanks for your help now and then, If this problem gets resolved I will be donating to this most excellent forum, awww helll I am gonna donate anyway, I am way past due for a Red R anyway...

Re: Parts Interchange 88-92 750 and 89-92 1100

When puting a '91 1100 crank in a '91 750 cases...... the crank journals are a different diameter. The 750 cases need to be line bored and new oil galleies have to be machined. I'm going a different route on the 6speed swap.
Would be cheaper to gring the 1100 mains down to 750 size.

Re: Parts Interchange 88-92 750 and 89-92 1100

Headlights/mounts are different also, obviously '88-89, '90 and '91-92 are different but '91-92 1100 are flatter and mounting tabs/studs in different locations than 750's (keep in mind since most h/lights you look at will be on a shelf, desk, in a box, etc. The '91-92 750's are more curved and are a bit narrower, if you find a headlight with all tabs/studs remaining consider yourself lucky ! They can be repaired quite easily if you have a airless plastic welder.
Oilcooled swingarms use a brake caliper arm attaching from the caliper mount, where watercooled swingarms use a mounting bracket for the rear brake caliper that fits into a sloted area on the inside of the swingarm, if you switch to a watercooled arm make sure you get the caliper bracket and any axle spacers they have
Engines- 1056 & 1127 external parts (starters, alternators, valve/side covers) are interchangable, but internals are different (duh) - 1127 GSXR cranks are lightened, Katana 1127 cases have more webbing/material around main journals, stroke is also different between GSXR/Katana 1127's (katana I think was 2.232 stroke) like to write more but at work -- will get back

So really, I can bolt on a set of '98 inverted forks to replace my crappy old '89 forks with no hassle? Sorry to beat a dead horse, but I want to be clear prior to shelling out the quid.

Re: Parts Interchange 88-92 750 and 89-92 1100

The way forward with front end upgrades appears to be L triples, '98 R1 forks, and thunderace front wheel + speedo drive +spacers, oh and some suitable clip ons.. at least this is the best I have been able to peice together from info on the net, will be doing this myself shortly hopefully

engine case covers?

I just got screwed on a Left side case cover. bought it over the winter when i was collecting parts for my '89 750... looked almost the exact same but when i went to put it on yesterday, I found out the bolt holes are just BARELY off, so it won't fit. Now I've gotta find another one and can't ride until i do.
What years engine covers fit on the slingshot?? i thought they'd be the same, cuz i thought the shortblock of 88-92 was basically the same. please lmk, cuz i'm scared to bid on anything on ebay until I find one. thanx

Re: Parts Interchange 88-92 750 and 89-92 1100

I am bit confused on this... I want to put a 91 or 92 gsxr-1100 front fairing on, not sure whatthis is called exactly, but it's the complete headlight section... will this work on my 89 1100?? what mods will I have to do to make this work...

Re: Parts Interchange 88-92 750 and 89-92 1100

Even cheaper still to simply use '88/'89 750 or 750Kat cases which run the 36mm mains.
