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

{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.}

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.

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...

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

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


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

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.
This is not correct.
All the 750's from '85-'91 have the same bore pitch and bolt pattern.
The 1100's from '86-92 run the same pitch and pattern.
1200 Bandits and 750 Kats are the same.
I believe the 600's also fit but I've not tried it myself.
The 1052 barrels fit onto the '88/'89 750 and 750 Kats but the case mouths need to be cut out to take the 1127 or Bandit barrel sleeves. The case mouths of all other 750 oilers need to be cut out to take 1100/1200 barrels.
The 1100/1200 crank fits into the short stroke cases but you need to replace the cylinder studs for the taller barrel and need to match up the clutch basket primary ratio to the crank ratio. The crank has 38mm bigends though so you either need to run the bigger rods or machine the journals down to take the 750 rods which also allows you to stroke the crank 2mm or 4mm. Running the bigger rods also requires the bigger piston pins so it's usually easier to swap the entire crank/rods/pistons/barrels across. 750 Superbikes sometimes cheated by running 1100 barrels milled down to the 750 stroke (you also have to cut 12mm of the skirts and you lose the front lower cylinder bolt making it obvious) with custom drilled pistons. The biggest simple swap is 1127 barrel bored to 81mm for 1003cc (or 921cc on the short-stroke cases) but you need to cut out the case mouths and run an 81mm piston blank drilled for the 20mm pin.
I haven't had anything to do with the water-coolers but do know the bore pitch is narrower - the crank is shorter and pistons sit closer together - so not much is going to be compatible.
Obviously I wouldn't recommend somebody try these sorts of mods without a very competent grasp of engine building.Changing one item requires looking at numerous other items to retain compatibility.

Sorry. The RF900 runs 34mm mains so only fits the 600 Kat cases unless you regrind the mains to 32mm to fit the '85-'87 and '90/'91 long-stroke 750's.
It's all very confusing :)

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

Hey Bones,

Wow you have some great info. This is my first time in the forums and I hope I am doing this right. My question if you can help out is I have a 1990 Gixxer 1100 (dual headlight fairing) and I was thinking about changing it to a single like the mid or early 90's 1100's. Is this possible without major modificatios? do you know what the first year single headlight fairing was for the gsxr-1100?

Thanks

91 or 92 750 upper going on a 92 1100.

Is this a clean swap? Plastic for plastic / screw for screw? I don't what to have to make any adjustments. I know the part #'s don't match, but the guy trying to sell to me swears they are the same.


Thanks!

I don't think that'll work. The 750 mids are different than the 1100 mids. So your upper fairing will likely swap with little effort, but from what I understand it will not line up with your mids.

99-02 ZX-6R Rearsets will bolt right up. You just have to do a little creative shift linkage fabrication and get a ZX-6 rear master cylinder.

Tested myself:

96-99 srad 600/750 4 pot calipers have the same mounting pattern as the 88-92 slingshot calipers

3.5" center to center

Tested myself:

gsxr 1k 05-06 shock mounts up to a 89-92 750 frame

The 1k shock is about 3/4" longer from mounting point to mounting point so please note there will be an increase in rear height

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

Tested myself:

The 2005-2006 CBR600RR shock bolts right up to the 89-92 750 frame with almost the exact same shock length. Shock stroke is reduced by about 5-6mm and stock spring rate is ideal for ~180lb.

This shock is obviously more ideal then the gsxr 1000 shock I mentioned above...please note that for either one you will not be able to use the battery box in it's stock location.

BRAKES---

Parts Unlimited online catalog lists that all brake rotors for the 88-95 GSXR 750 interchange. There are also other bikes that have the same rotors and are listed below.

REAR ROTOR (for GSXR 750 88-95)-

94-98 RF900
94-96 RF600
05 GSF650/S
99-02 SV650
92-93 GSXR600
89-98 GSXR1100
96-03 GSF600 (BANDIT)
98-02 GSX600F and GSX750F (KATANA)
03-05 GSX600F and GSX750F (KATANA)
96-05 GSF1200 (BANDIT) except w/ ABS
99-07 GSX1300R (HAYABUSA)


FRONT ROTORS (for GSXR 750 88-95)-

89-98 GSXR1100
92-93 GSXR600

So if anyone is on ebay searching for a deal but you cant find rotors listed for your exact bike these other ones will fit. Hayabusa rear rotors are cheap as hell! Still trying to find info on the slabsides. I know theyre not the same as the 88 and newer but thats it.
