Twinpot Brake upgrade on 78 Skunk

[bobgroger]

Just a quick question. Offering one of the brackets with caliper attached to the fork it looks like will fit with the original rotor. Is there a reason it can't be used? I do have a slight ringing bell in the back of my mind but can't for the life of me remember if there was a good reason for it not to. Also the thing that made me think about it was another conversion very much the same but using the drilled rotor.

Check post #546 for a list of rotors that will work. The GS550 Solid rotor in on the list, as well as some "L" models. The key is 296mm, most GS's are 275

Great! Hope the Post is quick for you. There seems to be no good reason connected to their efficiency or lack of it at times.

I made some space in the Inbox too!

Just curious if anyone ordered from Powersports Superstore. They often have a good price on parts but I assume they're too good to be true.

I've ordered quite a few times from them--no issues at all.

One back at ya, I can't see any good reason why it wouldn't work with that model.

If it doesn't I'll take them back minus postage.

Hi Salty Monk , does the brake caliper adapter plate fit the gs550 83 with twin brakes .

I have sent a pm .

cheers

No problem, glad you got them ok. Those Bikemaster units do look good.

[bobtail84]

My brackets arrived today thanks salty_monk. The calipers should be with me on Monday Apr 4 just need to source the rotors then have much fun fitting.

I can't speak to the quality differences but i certainly prefer the look of the Bikemaster rotors.
Could be they are both sourced from China.
To my eye wave rotors should only be on modern bikes.

[bobgroger]

I now have collected all the parts except the rotors. Wondering if anyone has used the Bikemaster 752 rotors? A little more than half the price of EBC, twice the price of Chinese wave rotors. They are made in Europe, and look very well built. Even the buttons are held on with E-clips so they can be rebuilt. A pair from Powersports Superstore is $255 shipped. Amazon has Chinese rotors for $116 the pair. WWYD?

Here is a picture of the actual Bikemaster part

I am thinking you get what you pay for, but this will never see a track.

Just for info, it is easier to look for ZR750 Zephyr calipers over here in the UK and they seem readily available. I've bought some for fifty of lizzies pounds and will see what they are like and report.

My bracket kit are on there way over the pond, thanks Dan, so all I have to do is track down are some serviceable CBR900RR discs / rotors. I'm looking forward to doing this conversion.

I have just read the whole of this thread..... What a truly inspiring read salty_monk has replied to my PM and the wheels are in motion for a kit to be sent to me in the UK.
I have found the calipers here in the UK for a good price and I'm still looking for the CBR900 rotors for the right money.
My GS1000 has passed it's MOT test on Saturday 03 19 (this is our road worthiness test) so I have a whole year of playing with upgrades. I will start a build thread to show how I've got to this Point and to show what is next. I do have quite a special engine to fit hence the brake up grade.
I have been truly inspired by the hard work of you guys in this thread, the information and ingenuity. Also a big hand for Dan as it was his hard work that has made this a viable solution for the somewhat iffy standard GS brakes.
