86 87 GSXR750 or GSXR1100 wheels on a KZ1000

I'm curious if anyone here has tried to run a set of wheels from a 1986 or 1987 GSXR750 or GSXR1100 on a KZ1000 (77-80).  

I thought I recall some folks doing the swap, but searching didn't turn up much.  I found 577nitro mention it here:

But it's been about a year since they have been active.

I thought maybe I recalled slayer61 doing the swap, but those were Kawasaki wheels that look a bit similar.

I'm mostly curious about how to fit the rear wheel.  I happen to have a GXSR750 rear wheel, with sprocket carrier and rotor included.  The KZ1000 rear axle is the correct size for the GSXR bearings, it right right in, I test fit the wheel GSXR  into a CALFAB swingarm I happened to have handy.  The wheel assembly fits between the arms of the swingarm, but it's a bit tight.  There isn't much room left for a bracket to hold the rear caliper.

The real issue is that the center of the wheel is substantially offset to the right side.  Comparing it to a KZ1000 LTD rear wheel I had handy, the GSXR sprocket is offset much farther away from the center of the wheel than the KZ wheel.  Just eyeballing it, It looks like I'd need to take between 1/2" and 1" off of the GSXR sprocket carrier to bring the wheel back to center, when using the stock KZ1000 sprocket and chain line.

However, the sprocket carrier is cast with relatively thin walls, and cutting that far down into the carrier would basically remove the mounting surface for the sprocket.  I don't think it's really practical to cut it down so that it has a similar offset to a stock KZ wheel.

Without making a custom swingarm, or finding one that was much wider, I guess then next option would to be make a custom sprocket carrier?  That seems possible, but not trivial.

I guess a middle ground option would be to cut the GSXR sprocket carrier down as much as possible, and then try to use an offset sprocket on the engine side?

So has anyone actually tried do put a GSXR750 or 1100 wheel on a KZ1000?  I really do think I remember folks here discussing this swap.  But maybe they hadn't actually tried it?

I need to take some pictures...


 

I a using a 600 bandit wheel in my 82 build- I have 13mm offset 530 sprocket on the front but still had to take 11.5mm off the sprocket carrier to run the wheel central

577nitro lays it out clear enough in his post. It sounds like it is gonna take a a bit of machining and fabrication on many components but fairly straight forward - assuming the GPZ1100 is reasonably close in dimensions to KZ1000. How much lighter are the GSX-R wheels than the KZ?

To the best of my knowledge you will definitely need an offset sprocket to allow the wheel to run central. The GSXR sprocket carrier looks very similar to the MK2 bandit item I am using (20mm axle) I have included a pic of my cut down carrier compared to a GSXR unit. The red line shows where the sprocket mounting bolts sit so still plenty of meat to secure the sprocket with 11.5mm removed. The MK2 bandit calliper hanger also has plenty of meat to allow trimming
