8track, is this master the one you used on your bike?

On the 550, yes. It's a 14mm bore so it should play well with the Ninja bits.

[Casino Joe]

Ahhh... now I know why you went to the bar-ends, no mounting boss on the master.
Do ya think it would play nice with my stock calipers and a pair of stainless lines?
I am wondering because you said the stocker should be 5/8" which is 15.875mm versus 14mm on the Katana unit.

No, I'm running bar end mirrors because of this fairing.

I used my old 550 mirror mount bracket on the Kat Master. (it threads into the master cylinder clamp)


I'm running the Kat master on my 550 with stock calipers and it works just fine.

The stock GS dual caliper set up did use a 5/8 master. The single caliper models use a 14mm master.
The smaller piston means more pressure. Bad part is, it has to travel further to displace the same amount of fluid.
That means the trade off will be a longer, and easier pull on the brake lever.

That is a very nice fairing, you have a beautiful bike. I'm looking at a Rifle Nightflight myself as my G will be a commuter bike.
I'll have to give the katana master some thought.
Nice trick with the mounting brackets, I learn something new from you guys every day.

82 650 rotors

Guys been watching this thread closely and am ready to invest. I have a lead on a set of 1982 gs 650 rotors.

The question? Will these rotors work on a single rotor 78 gs 1000. And will these work w/ the kawi calipers you guys have suggested or the gs 1000 calipers. My gs will be converted to dual rotor eventually one way or another.

Thanks for any advice.

Please understand, I'm not telling anyone that my way of upgrading the brakes is the only way. I can tell you what pieces fit together without a whole lot of fabrication.


Here's what makes it work:

The bikes that were equipped with a single rotor, use a larger diameter rotor than dual disk models. GS550, 750, 1000 doesn't matter, they all used the larger rotor. The mounting boss on the single disk forks is higher up to account for this as well.

The bikes that ran dual disks, and the little GS's like the 450 used the smaller rotors. Period.

My setup uses the forks from a dual disk bike, two rotors from single disk bikes, and the Kaw calipers.

Those calipers are made for a large diameter rotor. The largest GS rotor are barely large enough. Problem is, the brake pads on these calipers are not square. They are shaped like this )), very much like a car brake pad. There are two problems with using them on the smaller GS rotor.
1. They hang off the edge of the rotor.
2. You can't use the upper mounting boss on the fork, so a whole adapter bracket would have to be fabricated.

If anyone is going to that much trouble to make adapters, they might as well get a set of Brembo's. :-D

BTW, if any of you armchair know-it-all's have a better, cheaper, easier way, by all means DON'T JUST TELL US ABOUT IT. SHOW US PICTURES! =P~

Of course now that I think about your set up seems a bit more efficent

[8trackmind]

You are using an aluminum cross-drilled anchor, right?

[hp1000s]

That style of anchor is only good for urban, heavily-featured terrain...If you get out in the wide-open spaces, you'll need something much lighter and more easily deployed.

Quick Release.

Geez Jeff, I can't believe this mod goes up here and all we get at CM is the addition of a fairing?!?!
Guess Who?

Henry! :-D
I did post it on CM. Search it. It's there. Truth be told, I don't think anyone noticed, or cared. :?
Btw, If you need to contact me about that "special" part we talked about, here would be better. 8-[
Keep in touch.

[GSWeergin]

#-oI certainly missed it!
I'm working on reorganizing my garage space. We're adding a second floor! So I won't have to keep knocking my shins on dead bikes while I work to bring one back around. \\/
After that's done I'll go ahead and pull that part and send it on.

Cool! Thats one of my wife's Christmas presents. I get a bike, she gets a backrest. Seems fair to me. 8-[
