Yeah I’ve been around these styles of bikes for a while. Brother in law had been through quite a few bikes over the years and we both wrench a little bit. Personally have had 2 Harley’s and a bonneville. Still have my dyna.I’ll be doing a stem from cognito moto with a zx6 front end. Swing arm is to be determined. I am in no rush for this build. It will all be dealt with properly, mocked up and all that. I’d like to say I’m pretty OCD so skipping proper steps will not happen. 

I was born in the early 60's so I grew up with these bikes, had a pile of Honda 750/4's, old Suzuki's, Kawasaki's and a few in between...!I think the ZX6 only has about 25mm offset in their triple clamps, that'll take the nimble little 650 out to barge like Harley steering, kind of counterproductive on a little 650. I've had Devon at Cognito Moto {through a friend of mine stateside} , make me custom offset triple clamps to keep the steering correct on another long gone project. If you're using the 17 inch wheel that also changes things slightly, but will change things massively at the rear, it will put the chain line out miles, the 17 inch wheels are generally far too wide at 5 inches plus, a fairly easy swingarm conversion is using the Katana alloy swingarm, 2 small 2.2 to 2.3mm spacers either side, I used precision shims, and it bolts right up, it's a little bit longer than the stock are but not long enough to screw up handling.... Also fork length needs to be considered, most Jap front end swaps,  the forks are not long enough.  I've just done a couple of bearing swaps and made up new spacers to fit Kawasaki Z1300 wheels to a Triumph speed triple 45mm Showa front end , which is going on the front of a 1982 GPZ frame, I had to get custom made fork tubes 100mm longer to make the front ride height work. Nothing is as simple as it seems...My current project. 1st pic, the original bike, 2nd pic with swingarm and front end installed, 3rd and 4th pics are how it will look finished bar a pain job and the seat being redone..

Have you had any older bikes before ? or any bikes at all ? I ask because I'm also in Australia and parts are bloody hard to get here, and what you refer to as "junk" is quite usable.
I'd do it up as a stock SR650, they're quite rare down under . I've see harnesses far worse than that one.
Do you have any experience with front and rear conversions ? You can't just buy a front end or swingarm and bolt them on, it doesn't work like that. There's all sorts of geometry to get right, if you want it to perform well,  then there's mating wheels, chain line , bearings,brakes , spacers and a lot of other variables. I've done this multiple times and most,  {nearly all} , conversions I've seen are poorly executed... It's a lot of work to get right..

The GS{X}  1100 swingarm was made for a 17 inch rear  wheel, I have a 4.5 x 17 rear mag that fits in nicely, you won't want  anything wider than a 150/160 rear tire depending on manufacturer as the widths vary .. . There are plenty of 17x 4.25 spoked rims available, that would be fine for the 1100 swingarm.
If you're using a stock hub, chain to tire clearance  will be tight...  Measure everything meticulously ...

I run a gs1100e swing arm on my 77z1000 A1, it has a gsxr750 rear wheel running a 180 back tyre. theoretically you can find a Harley 5.5 aluminium 40 hole centred rim and lace it up but...you will e running into a fair few problems. The chain clearing the tyre for one, you will have to make a spacer to shunt the sprocket out to clear the tyre and an offset front sprocket to bring the chain out to be true. Problem will always be cause and effect, every change will have an effect that also needs to be changed untill its all right.

I recently purchased a 78 KZ 1000 a2, I want to go with a wider laced wheel like a 18x5.50. but when I try to find any that fit only Harley pop up. then says no compatible. any help would be great also I have 82 gs1100e swingarm.

Was able to get around to looking through my pictures for more interesting shots.
My son and I ran into a stuck slide in one of the carbs, so it took us a long time to get it out, but when we did there was this look of shock on our faces and excitement. He spent about 2 weeks with me last summer and then I did a bunch of work on my own (powdercoat, engine clean, rebuilding carbs) until Christmas time when he came out again and we put the motor back into the bike and rebuilt the swingarm. 

I've been working on putting everything back together since then. Ordered the motogadget blue from ebay, and the Revival Signature mo.unit Deluxe wiring kit ( this one ), dyna-s electronic ignition, and some new handlebar button controls. I finally got everything wired up and working last week. Started putting covers back on.Getting closer to getting her out on the road.

Things to finish up:
Front Brake line (getting an adapter for the new brake lines and new rigid brake line in the front has been a bear)
Need to make sure the gas tank with rebuilt petcock doesn't leak
Recovering my seat (doing it myself)
New tires (being mounted today)
A few other odds and ends

I think I'm pretty much settled on the black frame, I want to return the bike to looking as much like a 73 Jaffa as possible, so after de chroming is done, alloy items will be hand polished, some steel will be chromed (mudguards, headers etc) and other steel items (swingarm, front hub etc) back to black again.

I have dropped the barrel of at the engine place, the MTC sleeves have metal O rings in them that need replacing and it will require a light hone to clean it up.  As with most things mechanical these days there is a waiting list, in this case 6 weeks, but I still have plenty to do in the meantime.
I have stripped the head completely down ready for a hydrablast clean up but will have to wait for the barrel to come back so I can get that done at the same time. 
The pistons are cleaned up and all shiny, when I was measuring the pistons and bore, these pistons are actually 72.5 mm, giving a displacement of 1090 cc.
 

Back to the Z1000A1, with the XJR1300 swing arm narrowed, it was time for a test fit in the frame. Not unexpectedly, the pillion foot peg mounts got in the way of the now wider swing arm.. they had to go. Everything went together ok, the frame still needs to be braced, and a few other lugs and brackets removed or modified.[img] i.imgur.com/zDgGj2T.jpg[/img ][img] i.imgur.com/ZLTNsVX.jpg[/img ][img] i.imgur.com/JMDKz2R.jpg[/img ]

NOBODY sees the elephant in the room.
Chain and sprocket offset from the center line of the bike is smaller on the KZ400/440s compaired to the 4 cylinder bikes.
I have  put KZ650 forks and tripples  along with a KZ550 swingarm on a KZ400.
This gave me Twin disc up front  and 36 mm forks. On the front a KZ650 hub with a KZ400 rim. For the rear I used a KZ550 swingarm[narrowed] with a KZ400 hub in a KZ650 rim.
This is with spoke wheels. Since you want mags you will need to do what I did on one of my current projects.
I machined the hub from KZ750LTD down to fit a KZ440LTD and used a different width space to square itall up.
