Hi Reggie, is that Viking Exhausts in NZ?
Yes, Paul Bryant (Viking exhausts) built it for me.
It is based on a Dunstall 2-1-2, but I asked for the down pipes to tuck in more closely to the down tubes and for the single pipe underneath to run fairly close to the crossover frame tube. Also I asked for the silencers (peashooters) to run from a higher start point than the standard Dunstall and to more or less follow the standard Commando silencer lines/angles.
This has resulted in the rear "Y" piece just getting touched by the rear chain if I don't keep on top of chain adjustment, and running a 22 tooth g'box sprocket that I do doesn't help this.

Are you thinking of getting one?

Dunstall did make a cente stand for use with these, all they had was a loop to clear the bottom pipe, but sorry, no pics available.

Here's a pic from a Dunstall catalog in 1974

So, Dunstall used square tubing for the stand, unless my memory is playing tricks on me I distantly remember the stand with round tubes, but I could be wrong about this.
I did attempt to make one out of round tubes for another 750, but never completed the projet.
 
I have a 1/2 completed centerstand that I made from pictures. I used square tube. I ended up using a different exhaust so I never finished it. I might try to make another version to fit my new exhaust. I need to figure out some way for my bike to hold itself up. I am running Hooker TT pipes and had to ditch the center stand and the sideatand spring no longer fits.

I sent mine to Paul at Viking a few years ago after he caught on that I had one. He wanted to build one to go with the exhaust. Plan must've fallen through, though i don't blame him. I tried first to take pictures to send him but decided that just wouldn't work. In my opinion, you really need one in your hands. Especially if you are going to use it with the mounting plates and not try to make it work with the stock engine cradle. It's one above F, my shop is unheated and I don't think I'll be removing it today. There is plenty posted out here about the pros, there are none, and cons of this setup. Take the time to read these before you decide to mount one of these.
 
Here are pictures of the center stand off my bike. Contrary to an opinion regarding my previous post this IS an original Dunstall center stand. The bike (73 commando 850) was purchased from a Dunstall dealer by the original owner while he was in the service and I have the original title stating that the seller was Paul Dunstall, London.

Reggie, no , not getting the 2-1-2 made by Paul, my headers were made by him, I am lucky that he is only an hour or so ride from me, he made my headers and had them chromed, completed the ride to the NOC NZ rally after fitting them the day before a 1300km ride round trip, they have only just gone a honey colour at the top close to the head, no blueing as yet, top quality and fit a treat, mind you having the bike there helps!!! He showed me how he linishes them prior to being sent to the chromers, hence the top quality end finish.
Regards Mike

Uh, that would be me. :roll: I stand corrected. It is in fact Dunstall. That being said, does your stand have bushings where the bolts go through it and the mounting plates? I found another pair of plates and the holes for the stand appear to be a smaller diameter than the setup I have mounted.
 
No they don't have any bushings. The holes are all wallowed out, the bolts are worn, the stop pins in the side plates are bent and the spring is stretched. When I bought the bike the center stand was wired into the "up" position. I suspect the wear on the center stand bottoms and loop were a result of stand rubbing the tarmac due to the stretched spring. The side plates look like they were cut out with an ox-acetylene cutting torch.

If I use this setup again I will most likely remake the side plates with bushing and see if I can move the center stand to a position closer to the original location. The lifting geometry with this stand is all wrong.
