Are GS1100E Clutches Interchangeable?

[Guest]

Hi!
Would a later model (83 and up) clutch basket, etc. fit into my 1080 GS1100ET?
After glancing at the clutch section of this page:
http://www.hiredgunperformance.com/catalog/suzuki/standard/gs1100.html

I have noticed that there are 2 different models of clutch baskets: 80-82 & 83 and up. This leads me to think that there has been an enhancement.

P.S.: No, I'm not shopping for a billet clutch basket, Just wondering if a later model unit would be a good thing to do for my ET. I might have access to one from a GS1150 ...

TIA!

Hey, whaddya know! I'm currently in the process of a clutch basket refurb, and had some of the same questions. I believe they're mostly the same, in stock form. The link you have is to a place that rebuilds them, which seems to be a good idea, if you're going to be doing any engine upgrades in the future. I think the later clutches have a steel insert for the clutch hub sleeve to reduce wear on the aluminum from the clutch plates. I'm sure someone else will chime in shortly, rapidray will have a definitive answer if he turns up in this thread.

If your "access", means free, then I'd grab it just to have a spare.

yes...
chain or shaft will interchange within a few years/makes/models..

1150's only had the steel insert on the inner hub.

**has nothing to do with the plate/hub wear.**
**keeps the spline of the hub from twisting**

Interesting. I've discovered while working on this bike that I know just enough about engines to know that I don't know jack.

No LOL! I just think that there might be one available from someone in my neck of the woods.

That's good to hear! What do you mean by "within a few years"? Would, for example, an 86 1150 clutch swap (plug and play) into my 1980 GS1100ET?
Thanks!

Make sure if you start mixing and matching you watch the shim that Suzuki started adding in 83. A gorrilla nut and gorrilla hub are also very desirable.

The clutch hubs are not interchangeable. The gears are different.
The plates and steels themselves are though.

Bill I just checked the 80-81 GS1100E , 82-83 GS1100E and 83 GS1100S microfice and all of the current numbers used for the #1 primary Driven gear are the same 21200-49214 ; there are various old numbers listed and the
inner hub (#5 SLEVE HUB) have all been replaced with 21410-00A00. . The 80-81 has 3 inner sleve numbers listed that are now replace by this new one 21411-49201, 21411-49202, and 21411-49203.

The manual says that #3 Spacer 21251-49200 is shorter on the 83's but there is no evidence in the micro fiche.

I only have 83's; anybody ever measured the thickness of the #3 spacer on the earlier motors? It should be 1mm thicker than the 83's

EDIT: I spoke to Rapid Ray he seems to think that the 1mm+ thrust washer is not too common and olny exists on some of the late GS1100ED's and the 83 GS1100SD's. Both of my ED's have it.

I was referring to the 1150s and 1100s.

Thanks for the insight guys! As always, this info will be very helpful!

POSPLAYR how can you have TWO EDs?
Gary from the backwoods I guess.

He used to have three.

don't rely on fiche and such all the time.
hands on is the best method of knowing interchanging parts.
83 had the thinner grooved washer(plus a 1-2mm shim) as did all the 1150's.
on 80-82 you didn't need the extra 1-2 mm shim but it is a good idea to add this shim to keep from shearing the back off of your inner hub during power shifts/hard launches.
on 83 and 1150's add a 1-2mm shim as i have brokin 4-5 inner hubs on 1150's before a well known racer(jessie gatlin) told me how to fix the problem many many moons ago.

So it is the grooved washer that is thinner on the 83 to compensate for 1mm+ shim? The parts microfice shows the same number for #8 on 82-3 GS1100EZ/ED/ESD and the 83 GS1100SD to 80-81 GS1100E

parts bike; Bill got the Yellow banana and the motor runs like a charm. The other Blue Belle only has 15K miles and Bill was brave enough to pop wheelies on those old tires

It would have to be the spacer that rides in between the bearing that is thinner. Outside the hub would make no difference. Jim and I tried to install the notched washer only because the other didn't show in a micro-fiche and the washer locked up the clutch by pressing on the id of the hub so the inner spacer is different.

Ray claims the #3 inner spacers are all the same size

If the hubs are the same and the large washer is the same then the only difference is the inner spacer. The added washer is the same diameter of the inner spacer to make up the difference as otherwise the larger washer just presses up against the hub. This is the only thing that makes sense to me in this matter.
