I bought some universal Tarrozis from Jim Hinshaw on Ebay, the linkages I cobbled together from bits I found/bought/modified. The one problem no one seems to mention is the loss of leverage on the rear brake, the original brake lever was nearly a foot long, compared to the six inches or so of leverage you get from using rearset levers. I took the huge return spring out of the brake but it still needs a good bit of pressure to really bite on the disk. I need to make the brake linkage out of solid bar as there is still a fair bit of flex in it using 8mm threaded bar.
