Twinpot Brake upgrade on 78 Skunk

[Chuck78]

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

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

EBC HH pads.

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...

[greg78gs750]

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.

[limeex2]

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?

[RobAwf]

Will 2001 CBR900rr rotors work for this application?

[salty_monk]

Chuck welded the original brake bracket & extended it then did a very good job of blending it back to the original metal. Looks great. Doesn't appear that there was any heat damage.
You need to trust your welder if you go that route! Grinding the welds to finish them would make for a very weak bracket if you do not have full penetration of the weld.

I think the HH's are designed for rotors like the CBR's - wear will be higher but it's a trade off.

I think they are a different diameter.

These are the lightest ones that are compatible if that is what you are looking for:

These work too:

Have a few sets of brackets on the shelf if anyone is in need although I Can't ship any until end of August due to schedule.

I believe it was mentioned in this thread that these will work with GS1100GK forks? If so I need a set.

@salty_monk I'll send you a PM in a moment.

Edit: previously said that I was using GS1150 forks...

[salty_monk]

Yes they should work fine on any 1100 fork. The 1150 fork is different. Responded to your PM (about the 1150 forks) but have brackets if you need some for 1100 forks.

I was under the impression that the GK calipers had a slightly different offset compared to the other 1100s. I definitely need a set of brackets if they'll do. I replied to your PM.

[salty_monk]

The L models do but I'm fairly sure the GK models don't and I'm also fairly sure someone else here used them on a GK.

If they don't work out you can send them back to me if they are not damaged, just pay postage (and any Paypal fees).

[salty_monk]

Have some more brackets ready to go if anyone is in need.
