1150 3.5" wheel in an 1100 swingarm

[jfman]

W/O narrowing nothing fitsw in a GS400...

Needs 3/8 removed from both sides of the pivot.

I just hope it isnt so wide at the axle that it hits the pipes.

The gs400 swinger is 7 15/16 at the pivot.

hi guys, i hope no one will mind if i add a bit of hijacking to this thread....i have my own going BUT this one has all the info in it, so i am hoping to get this figured out. Just spooned a new rear tire on my es, tck's old bike, and in thoroughly checking things out, i have discovered some....irregularities. This bike, to remind you, has undergone the 1150 rear wheel swap. In putting it back together, i have discovered the rear wheel is offset to the right by, oh, 5 mm or so.

let me see if i understand the first part of saltymonks spacing recipe: a 2mm spacer between the sprocket carrier and the wheel? pushing the wheel (further?) to the right?

You need to add 2mm between the bearing & the sprocket drive spacer on the left side (to push the wheel slightly to the right)

my wheel seems to need to go to the LEFT.

furthermore, if i shift things to the left, it seems that my countersprocket will need to shift left, too, problem is there is VERY LITTLE meat left on the countershaft spline, maybe like 1 mm or so, certainly not the 5mm it needs.

i am sorry i am being dense here, i know all the info is in this thread, i'm just having trouble sorting it all out. thanks in advance!

i will try to get some pics up tonight....

some pics, hard to see, but you can see the wheel is offset to the right quite a bit
and the other side

[greg78gs750]

ok, after reading carefully through this thread, i would say that MY 3.5 inch 1150 wheel is similar to john's, and as such is offset to the RIGHT by about 5mm, from what i can see here his recipe of shaving down the LEFT, drive side spacer and adding the difference to the brake side is correct for me. this is all going by just looking at it with my eyes, not with any real measurements. but, based on what i SEE, this is right. john, i think a pm will be headed your way soon, i am not sure how to deal with the countersprocket needing to move out. i gotta believe i want full engagement of the splines.

[greg78gs750]

incidentally, and just to drag this thread further into hijack mode, i am going to be doing the twinpot mod this winter and am sure to have more annoying questions for you, dan! have my parts collected and ready for cleanup/paint/etc!

I must say, I'm glad to see that I'm not alone on this one
You are definitely right: you shave 5 mm off the LEFT side spacer, you add 5 mm to the right hand side but now your chain engine sprocket needs to be moved out by 5 mm.
It's very easy to do: you add a spacer behind the engine sprocket.
This spacer can be found at Z1 enterprises as it's used when you replace the OEM sprocket ( allthough in the std application it goes on the outside of the sprocket whereas here it will go on the inside).
There is enough thread on the sprocket shaft if you remove the noise dampening rings off the OEM engine sprocket!
Would you know the exact origin of your 3.5" wheel?
The Z1 reference for a 6 mm spacer is TU24-9325.

ok, ok, ok. hang on here. something is not right on my end, maybe my chain is not aligned as well as i thought. also, maybe i need to take some more pics and take some measurements.


ok, so on my bike, an 83 1100 es, this mod was done by tck about, what, like 3 or 4 years ago? i have been running it basically as-is for 2 years now.

it has already gotten a 530 sprocket and chain.

it also already has the spacer BEHIND the engine sprocket, with the sprocket unadorned with any damping rings. it pushes the sprocket out to the end of the splines. pics to follow.

bear with me, guys, i just want things right.

[greg78gs750]

ok, some pics



notice the wear on the sprocket. obviously i had some alignment issues there. im sure you guys are gonna tell me to replace it.....
similar wear is seen on the inside of the wheel sprocket, as you would expect.





the spacers measure about 16 mm for the one outboard of the brake stay and about 28 for the chain side. the engine sprocket spacer is indeed 5mm.

[John Kat]

The spacers are the standard ones for the GS 1000 at least on the left hand side.
The one on the right is larger to take into account the smaller bearing to bearing size of the 1150 wheel.
Clearly the 5 mm engine sprocket spacer was placed on the wrong side of the sprocket for the std 1100 wheel configuration
I can't imagine the state of the chain...

[greg78gs750]

anyone have a good source for spacers?

do yourself a favor and see if the chain is aligned with the wheel. This construction level is pushed against the tire and compared to the chain. The sprocket carriers are not well aligned and a laser of the sprocket is not accurate.

[salty_monk]

In a 530 chain CONVERSION the spacer goes on the OUTSIDE Of the drive sprocket (small one at the front) NOT the inside. (makes sense when you think about it, the rear sprocket hasn't moved at all...., it's inside edge is still flat to the sprocket hub so all the width (sprocket width) that is lost is lost from the outside NOT the inside).

Switch the spacer to the outside of the sprocket & your problem will disappear it seems to me....

By the way TCK put all his spacer on the RIGHT. You would be better moving half of the spacer to the Left between the wheel bearing & the drive hub Spacer. (Right now your rim will be offset about 2-3mm to the left but I am sure in practice you probably don't notice that when riding).
I am very confident that TCK's wheel measures up the same as mine from the threads he posted. If you do this.. check clearance on the RIGHT after you've done it as you'll be generating chain to tyre clearance on the Left & losing brake stay to tyre clearance on the right by doing this.

John - this is a different issue to yours

i will do this tonight.

hi dan, glad you have chimed in.

listen, yes, josh added spacing to the right, but, im telling you, my wheel is offset to the RIGHT, or brake side, as it is right now. take a look at the pics, i havent measured it (will do so tonight) but you can see the offset is obviously to the brake side of things. this is with no additional spacing to the drive (left) side:

drive side: you can see the tire to swingarm clearance if you look carefully


brake side: obviously less clearance


i will tacke some more measurements and pics when i get home tonite if i can get the kids off my back for a minute.

havent been this excited by the forum in a couple years! nice to have a problem to solve, sometimes i feel like my gs 's are too reliable

I'm not so sure
The PO obviously mounted the spacer for the engine sprocket on the wrong side but on top of that the 1150 wheel appears shifted to the right...just like mine!
The chain to tire clearance does not change if you narrow the LH spacer.
The chain will of course have to move out by the same amount.
And that's when you use the spacer on the other side of the engine sprocket.
