What are you putting these on again? Sorry i dont think i saw what model GS you have. Im not all that observant at times :)

As far as the 750/1000 spoked rims:

Front 19inches
Rear 18inches

The fronts came STOCK with only single sided disc, BUT, the holes are there for a second disc, you just have to usually remove a silly plastic hubcap.

The rear on ALL the 750s (except for the 750T, which was a goofy lil "entry level" bike they put out in the early 80s) and 1000s were disc.

Now, if your bike currently has DRUM brake in back, you will have to do some minor mods. Depending on what model you have (again, sorry) you MIGHT be able to get a 750 swinger to fit back there, in which case, all you will have to do is figure a way to mount your rear master cylinder (tho if you plan on putting some modern rearsets on this project of yours, that too is easily taken care of, and the rear master generally comes built into the brake side set) and you'll likely have to change out the brake pedal (again, if you're doing rearsets, this is all taken care of with some gixxer or busa 'sets) You'll have to figure out some offset issues with the chain and sprockets perhaps, but its not impossible. Just takes some planning, some imagination, some skill, and always, some help from a buddy, and from those here who have done such things.

On the front, you'll need to find a set of forks from a 78/79 750 or 1000 with dual disc. In 78 the 750 got cast wheels part way thru the model year, and THOSE had dual disc, so the forks are obviously set up for that. The 77 750 had only ONE disc, and im not positive on the 78 1000 (first year for that bike) on whether or not it had dual disc, laced rims or single like the first year 750. Again, depending on YOUR bike, could be as simple as a matter of a steering bearing change. Hell, they could bolt right on too...
 
Simple swap then. Just find a set of 750/1000 rims, and put new wheel bearings in em. The rotors should work just fine.
 
Another aspect of spoked rims that I am not finding a source of info for, How may spokes?
Most of the Jap bikes are 36 hole rims. Many Euro bikes are 40 spoke.
But I am finding full size rims with 32 holes, What bikes would they be on?
 
Excellent link to this list, cheers!

They don't list axle size for my '81 GS450, but I have the manual so I can find out easy enough if I want to change to spokes...
 
I would expect them to be 15 & 17 as with the other mid size GSs. The 1000 has a 20mm rear.

I see the MX bikes are where the 32 spoke wheels are from.

20mm rear on a GS1000? i must have read it wrong, or the GS1000 is double listed.
 
aw crap. the shaftdrive bikes are 17mm rear. i just bought wheels, the front will fit, the rear is a 17mm rear. can i get an axle and spacers for a 17mm wheel and be okay on my 79 GS1000, or do i need to find another wheel?
 
If I read your question correctly, you bought a wheel with 17mm bearings that has to go over a 20mm axle?

evidently i did. i have now found out the gs550e is drum rear. another bummer. i guess i can buy the 17mm axle, and convert to drum:(

No, the GS550E is disc rear. The base 550 was drum. The 550L uses a 17" rear wheel.

its an 18" wheel.

That is base model, the E has alloy mag wheels.

Check the OD of the bearings, probably 40mm but if they are 47mm you can install 20mm ID bearings.
But I expect you are better off getting a disc brake wheel, unless you want drum.
 
'77 GS 750 had spoke wheels and a single disc on front and also a disc on the rear. Making them dual disc was easy and involved getting the right side fork lower, caliper, disc, and hose from a later model.

Getting these parts would be the easiest way to get where you want to be. Lots of '77 GS 750's in poor shape are getting parted out these days...
