Seems that everyone doing this is a machinist, I am not. Can the bushings for the swingarm swap be purchased? Would any of the experienced builders be willing and able to tackle the stem work for $$?

There are some swaps that will bolt in. I was a 98 GSXR 750 with a bearing swap kit from All Ballz, my build is in my signature. I would suggest the GSXR 1000 of the same years as the forks are longer. I did not know this when I bought mine. There is a conversion table available on All Ballz Bearing that will help you determine what will work. What it won't tell you is stem length. The 98 GSXR 750 stem is a little short. I recommend taking the time to read through the builds to see what works without machine work. I want to say there is a ZRX swap that works but I'm not certain. Good luck.

Beautiful bike. Congratulations. I wish you good riding.

The steering damper has a mount built into the steering stop, and I have not installed a damper yet.

You've kept me a member to this site for how long? It was worth it. Bike looks tits, and who doesn't like tits? Great job.

Troy was a great help in the beginning, Troy is not afraid of any project, and helped a great deal with the GSXR language. It is "tits" Troy, thanks for your help.

Thank all of you who have posted encouragement. there have been a few nights I wanted to hook a tow strap to it, and drag it down the street.

Can't wait for spring.

Looking great! How does it ride?
Did you ever figure out a mount system for the steering damper?
And did you paint your engine silver or just clear coat?..

2 wheels are heaven!

Thanks for the great read!

Okay, so while fiddling with my rear end (er...) I found a caliper hanger that matched the spindle diameter, but which needs some machining to make it the right thickness for what I'd discovered on the left hand side of the swinging arm. And I bolted on an SV650 caliper I hand hanging about.

I dunno if you can see here, but it's right for the offset of the disc (zero) but not for the 210mm diameter.

So, with some guesswork and a ruler waved in it's general direction, I reckon I need a disc of 230mm diameter. Either that, or get a new caliper hanger made, and I think that the disc is the easier option! So, anyone know of any online disc dimension lsitings? Some quick measurements show that the disc fitted to the Dymag is a six bolt fixing (so a three bolt one would also do the trick) of PCD 109mm, with the central hole being 99mm diameter.

When the Dymags were first fitted, I got some bloke to make up the wheel spacers,along with the caliper hangers for the Yamaha blue spot 4-piston calipers, and a rear caliper hanger for another blue spot. But, at some p[oint, I decided that I didn't want a big 4-potter on the rear, so threw away / lost the spacers and hanger. So, I needed new ones.
So the rear wheel needed centralising and measuring up for some spacers...
Hmm, looks a bit close to the swinging arm on the left.


The shock mounts and centre casting mark on the Dymag gave convenient reference points.


Stacks of room on the right hand side, and I'll get a mate to machine up a spacer before I start thinking of a caliper hanger (mainly because I don't know what caliper I'm going to use yet)


So it was all measured up with the wheel in place and a couple of spacers ordered. When they arrive I'll be able to bolt it together solid, and check for chain alignment...

You may not be able to tell from the pics, but once it was centralised there was a bit more room between the sprocket carrier and the swinging arm...

That's my opinion Pete

You've got the poor thing condemned already! :woohoo:

I've been vintage racing a '75 Z1 for 10 years.Started out stock and as I improved I switched to racing rubber and then the problems began.The street Metzlers would slide predictably when pushed but the sticky rubber transferred the stress to the frame and became dangerous entering high speed corners(front became vague and would run wide).My buddy found what looks like the same info from Japan.I made cardboard templates and then cut out the metal and my buddy welded them in.I took a front end off of 6 cylinder shaft drive and replaced the stock front end and put in Progressive springs.Mikes XS (Yamaha) makes emulators for the 650(cheap $60) .Too small but we made a recessed washer the right size for the larger forks.I found a Suzuki box section swing arm for $50 to replace the stock.By moving the forks up in the triple clamp I found where they work best.The bike works far better than I expected and is great fun to ride.I actually touch my knee down now..My buddy and I got a podium in the 3hr endurance at Grandbend last summer because the it worked so well.Cheap but worthwhile fix.
