Updated 85-87 750 and 86-88 1100 parts interchange

Well....the interchange we had is lost. Have to start rebuilding what we had so If you have any known swaps for slabsides please post them again here. No questions please....post those as a new thread in the main forum.

THIS IS ONLY FOR KNOWN SWAPS!

The 88/1100 has a 17mm front axle!! It's a typo!!

Re: Gotta start somewhere.....Slabbie parts interchange.

'85,'86'87 750 and '86-'92 1100

Okay,Front brake and Clutch Master cylinders... "01 - '04 Bandit 1200"S" both sides, direct swap,levers and all.

'99 - '07 Busa both sides, direct swap levers and all.

This gives you updated adj. and easily replacable levers at the same time. And they look indentical to original Master Cyl. And are made to work with 6 piston calipers as well. For those of you swapping 6 pots onto your bike.

Re: Gotta start somewhere.....Slabbie parts interchange.

The lowers from '86,'87 750's physically interchange with lowers from '86,'87,'88 1100's

Lowers from an '85 750 interchange with none of the others.

Re: Gotta start somewhere.....Slabbie parts interchange.

The upper fairing from a '86-'88 1100 is about 1/2" wider at the mirror mounts than a '86,'87 750.

I have had luck interchanging them as long as the correct rear fairing support is used. As the 750 and 1100 supports are physically different from one another. But either one will bolt to either frame.

Re: Gotta start somewhere.....Slabbie parts interchange.

The seats and solo fairing are physically interchangable between '86-'87 750's and '86-'88 1100's

You can put a '85 seat set on the '86-'88 slabbie's by taking the rear seat latch and moving it to the front cross member, then removing the old front latch from the latch cable.

So then, you can fit a '86-'88 slabbie seat on a '85 by getting an entire seat latch assy(part that bolts to your left rear peg mount,along with cables and both latches) for a '86-'88 slabbie and installing it on your '85. Long latch on the front cross member, short latch on the rear one. It's that simple.

Re: Gotta start somewhere.....Slabbie parts interchange.

****USD FORK SWAP****

With a set of '91 750 triples you can swap a '01-'03 750, or '01-'04 1k front end onto your slabbie. This type of swap takes considerable mechanical knowledge to finish out all the little details. As the 91-92 triples are approx 7mm wider than the 01-03 triples, so you will need to make wheel and caliper spacers at a minimum. If trying this swap, get a COMPLETE front end. It will make your life much easier.

The 91-92 750 triple will also allow you to swap in the 91-95 750 front forks also.This way will allow you to keep your mech speedo drive.

All GSXR 750 triples from 91-95 will allow you to do these swaps. But 93-95 triples will require steering stop modification also.

Re: Gotta start somewhere.....Slabbie parts interchange.

The mid panels will physically interchange between the 750 and 1100 with one modification.You will have to drill a new hole for the bolt that goes into the side of the head. The hole for the bolt that mounts to the head is in a slightly different location between the two due to differing cylinder heights.

Re: Gotgixxers 85-87 750 and 86-88 1100 parts interchange.

OK some basic stuff to most of us but here are a few basics. The information pertains to US models and other countries will have some different combinations so always double and tripple check. This is a starting point.

85-86 750's and 86 1100's have 15mm front axel's
87 750 & 1100 have 17mm front axel's
88 1100 has 20mm front axel as does 88-94 750 & 89-94 1100
so for rim upgrades on the front the 88 1100 front end is easiest to retain the 41mm fork tubes with 17" rims or Slingshot front end (43mm tubse) or 91-92 USD (up side down) forks allow the 17" front rim. The 750 USD's are 50mm tubes and the 1100 USD's are 52mm tubes.

85,86,87 Engine Ignition and Starter clutch covers interchange with the 86,87,88 1052 motor as well as the 88 89 slingshot motors and the 90 91 92 GSXR 750 motors. These covers are the same for the Kat 750 motors and bandit 600 motors
85-92 GSXR 750
86-88 GSXR 1100
96-04 GSF 600 Bandit
89-06 GSX 750 Katana
88-06 GSX 600 Katana

The 1127 Ignition and starter clutch covers interchange with the bandit 12 motors and the Kat 1127 motors.
Bandit 1200 96-06
Kat 1100 88-93
GSXR 1127 89-92

Rear Sprocket 6 bolt are 92-95 GSXR 750 & 89-98 GSXR 1100
Rear Sprocket 5 Bolt are 85-89 GSXR 750 &
86-88 GSXR 1100
92-93 GSXR 600 WC
89-95 GSXF 600
89-95 GSXF 750
94-95 RF 600

Rear Brake rotors interchange for
220mm rotor 85,86,87 GSXR 750
.................86,87,88 GSXR 1100
220mm rotor but thinner 97-07 GSXR 600
..................................96-07 GSXR 750
..................................01-07 GSXR 1000
..................................03-07 SV 650 & 1000
..................................98-03 TL & TLR 1000

240mm rotor 88-94 GSXR 750
..................89-94 GSXR 1100
If you want to run a different diameter rear rotor you need to use corresponding rear brake hanger.

Re: Updated 85-87 750 and 86-88 1100 parts interchange

Starter clutches, although slightly different, interchange between the 1052 and the 749cc motors. To use the 750 starter clutch in a 1052 motor, use the 750 starter clutch, the 750 intermediate gear and the 750 starter motor as the 1100 items have different numbers of teeth, looks like 1 tooth different on all components.

Re: 85-87 750 and 86-88 1100 parts interchange ~ Flatslide Drain hoses

Anyone who has the flatslides on their slabby knows about the dripping of the float bowl drains.

According to our local Suzuki shops, the hoses that redirect the drains have been discontinued however, I found a guy who knew what he was doing and he gave me a part number for a hose that fits.

Suzuki Part Number 09351-30503-600

It's about 15" in length so plenty of extra length.

Re: 85-87 750 and 86-88 1100 Parts Interchange Info

Known Swap for those wanting original Mikuni BST31 carbs is:
1987 and 1988 Katana 600 carbs are the same. What is nice is that if you want to use your stock air box, these carbs are 50mm in back and 31 up front same as original GSXR 750. When looking at Katana carbs, if the vacuum slide lids have 4 screws you are good to go. The vacuum slides are slightly smaller and are not interchangeable. You may be able to remove the side guides for the slides and swap them or use them as is. You will have to drill the main air jets in the back out to 1.7mm as they are smaller. Obviously change the Main jets, needles, and the pilot jet should be the same 32.5. I'm not sure but the 1100 Kats of the same year may also be the same.

So, I can use a complete fork from a '92 750 gixxer on my '88 1100 gixxer ? Just swap it ... right ?
That's what I am about to do, but I have to be sure. The length and thickness of the Steering Stern should be the same. Right ?

Re: 85-87 750 and 86-88 1100 Parts Interchange Info

Thinking of buying an 86 gsxr 750.

What's the easiest way to get more modern wheels and tires? Any later model wheels that bolt up fairly easily? Has anyone tried wheel widening? I know there is only one company recommended to this.

Thanks.

Re: 85-87 750 and 86-88 1100 Parts Interchange Info

I'm working on a 87 gsxr 1100. Currently have a complete 2000 gxsr 750 front end. I saw that most people stop at the 5.5 inch rear wheel. I bought an 08 Hayabusa 6 inch rear. Anyone know which swing arm will interchange with my 87? Possibly the complete Hayabusa arm maybe?

Awesome sounding build.

On my 85 GSXR750 I stopped at 5.5 with a factory swinger with an adjusted/bent brake arm. It allows me to put on a fat 180/55. Why don't you start a new post and ask for advice on swing arms for 1st generation 1100's. You'll get more results that way than posting in the interchange.

you need a offset front sprocket ,than you arrive closer to the frame with the chain
6 inch in slabby is possible but is never a good idea
no oem swingarm are a straight swap
but with few mod all is possible even a LONG busa one

Re: USD conversion

This is from Awasson and I thought it would make sense to have it in here.

I swapped my 85 750 over to 94 GSXR 750 USD and 17" rims over a 2-day period and it was quite simple. The front end is quite easy because the steering head, bearings, etc... are the same diameter. It almost drops in without issue however there are some things to watch for:
The steering lock will no longer work because there's no easy way to transfer the lock over from the OEM bottom triple to the new one. A disk lock is a good solution.
You have to remove the steering stops (horns) from the USD bottom triple because they will scrape and bind against the frame.
You have to remove the 2 mounting points for the ignition switch on the USD upper triple and drill/tap new holes so that your ignition switch will fit.
You will end up with less lock to lock steering movement with the USD setup because they are much beefier than the OEM forks. When you do the swap re-route the electrical and speedo cable around the cockpit so that it is well clrear of the fork left/right movement and it should be ok.
You may find that you need to lower the clipons on the USD front end to account for the openings in the upper fairing. It will likely be pretty minor though.

Doing the rear wheel is easier. I used the 94 axle, spacer, cush-drive, sprocket and rear disc and it pretty much just bolted right on. I used the OEM rear caliper with the 94 disc and the only thing I had to deal with was adding more curve to the brake torque arm so that it didn't rub against the much wider rear tire.

It's an amazing upgrade
