Twinpot Brake upgrade on 78 Skunk

Will 2001 CBR900rr rotors work for this application?

I've run HH's for 40k on my Triumph with no rotor issues. Break in those pads on the street before you go to track day. 2-3 blocks before home, I'll ride the brakes and then let 'em cool down. Chuck, in the 1st picture, it looks like you don't run a bracket, straight bolt on?

yeah, I've been running the ebay cheapies for a while, but i need new pads for an upcoming track day. Any concerns with the ebc hh's and rotor wear? I have been looking, too, at ceramic, but I've not had luck finding decent ones.

[salty_monk]

I've used a variety of pads. The stock Tokico ones are actually pretty good.

I've used some HH's some organics and some Ebay cheapies. Generally you get what you pay for but all are better than the stock Suzuki setup...

[mmattockx]

what brake pads are you guys using in these, other than the ones that came in them or the ebay cheapies?

EBC HH pads.

Chuck, think you could do an in depth review of your gs750/920, the whole bike? On it own thread of course?

Look in the recent few weeks of the "Post pictures of your custom GS" thread on here in the Appearance sub-forum.

I listed all the mods I have done over the years to make that sort-of-stock-looking bike into a fine handling sports/tourer. My idea of touring does not include hardcase saddlebags, luggage racks, big windshield, etc... by sports touring I mean I load a minimal amount of backpacking gear onto my bike and tools / food / rain gear in saddlebags and head for the mountains!

It's a very fast 750, I often think I need to do more mods (head ported by Rapid Ray sometime soon, mega cycle cams) because it's "not quite fast enough yet" & then I ride with other people or ride other bikes that I used to think were really fast, & I realize mine is really really fast! My buds on a 2000's Ninja 750 and a ZRX1200 can barely keep up with me in the twisties and can just sneak by me on the highway as they slowly pull ahead. They are thoroughly impressed with how fast I can pull away from them or pass cars. It pulls well even at 115+!
With GS850 pistons / pods&pipe / careful re-jetting it was a rocket at high rpms and would hang with modified KZ1000 1132cc quite well. He was actually very impressed at how fast the bike would go when downshifting and burying the tach needle through the gears above 5500rpm-9000 or so. It revs to 11500 well while still making power. With bigger pistons I try to keep it under 10000rpm now.
At 920c it's an absolute street menace. I try not to ride it in the city much as I just screams for me to twist that throttle grip backwards rapidly... it's a bad influence on me for city riding!
A 77-79 GS750B/C/N/EC/EN with brake&suspension upgrades, Wiseco K844's, & Megacycle camshafts is one heck of a package if you don't have any GS1000's available or just want a slightly smaller bike than a 1000

Thanks Dan for the awesome brake research you have done! I can ride faster more confidently for many years now than if I had stock GS brakes... Very crucial, and very good looking brake package!

Nice! Shame the exchange rate is in the toilet or it would be even better!

Thanks Dan, I'm in the states in August and I'm going to order the Racetech emulators as they are a lot cheaper in the USA and take them back to blighty.


Looking good Chuck, looks like a great road to ride from the pictures.

I made up some adapters & ordered the ones from MikesXSthat are made for 35mm forks. A little cheaper that way... https://www.mikesxs.net/suspension.html

Being a lightweight I cut down some stock springs to give me about a 43lb spring.

[bobtail84]

Looking good. I have straight weight springs & emulators fitted - they help with dive too.

I have Hagon progressive springs in the front and they do dive a bit under breaking with the new set up. I don't suppose you remember what the code was for your emulators do you Dan?

[salty_monk]

You should make sure that stainless bolt is an A2-70 one & not made of Cheese but I wouldn't have a problem using the standard thread as long as there is a locking element or threadlock.
The load is 90 degrees to the thread so the only real benefit of the fine thread is vibration resistance (and more threads in the thin caliper bracket but as this is the one with the nut on it that's not applicable here).

Looking good. I have straight weight springs & emulators fitted - they help with dive too.

The progressives with the close together coils lopped off are about a 50lb/in spring (approx 1.0 KGmm from memory, you can google that) so that might be a cost effective option for you if the spring rate is right... Replace what you cut off with Schedule 40 pipe.

Another angle a little closer up...
