Perhaps some sort of adapter plate is required.
My brother has a 6 pot Harris brake fitted to his R100GS. Seems to work ok. But then it was the correct fitment.
Are you running a single disk?
The normal route is to improve the dual disk set-up with stainless lines and after market disks, etc.
On my 79 I am running a single Brembo and a floating disk. Not as powerful as a dual disk set-up, but I have grown to like the progressive nature of the brake. I had to change my master cylinder, from the round ATE to a later rectangular Brembo type, but still keeping my twin pull throttle. A little bit of fettling required but not a lot.
I am also running banjo connectors, as I used to run two calipers using only two hoses, one from the master cylinder to the right caliper and the other from the right caliper to the left. I did away with the front brake light switch.
However a single 4 pot caliper would improve braking without increasing the unsprung weight much - i.e. having the extra disk and caliper on the front wheel.
How much volume of fluid does a 4 pot K series caliper require as opposed to a Brembo two pot caliper? Just curious.
I am interested in this.
Cheers
Rev. Light
