I added a second front caliper/disc to my GR650. I replace the right outer tube with one from an '83 650G to get right caliper mounts. The way the front axle fits into the right fork is different than the original, so there was a bit of work to make the spacing correct. When I mounted the caliper, I had to add 5 washers between the fork and the caliper to get it to line up correctly on the disc. The disc I fitted are the same as the one on the left and these are same as the GS850G and GS1100G ,and the GS650g, so it is a common disc. The question is this OK? should I be concerned about flex? I bought some longer bolts so there is plenty of thread in the caliper. Here is a picture.
