QuestionI have a 77 KZ1000 A1 which I am rebuilding from the frame up. Along the way, I got a pair of mag wheels from an 81 KZ1000 J model. Unfortunately, the J model has smaller rotors than my 77 A1, and they bolt to the wheels differently using a 7 bolt pattern instead of a 4 bolt pattern.
I was wondering if there are any oversize rotors available for the J model. I am looking for about 11 1/2" front and 11 1/4" rear with the 7 bolt pattern. It could be something specifically made for the J model, or for another bike. I would even consider having a new center made up for the existing A1 rotors. Barring any of these things, are you aware of any manufacturers of custom brake rotors?
This part of the project has been by far the most difficult and I am now into it up to my neck!
Another option would be to replace the rear caliper with a smaller one, and replace the lower fork tubes. The only problem with this is that I wouldn't know which ones to go with, and I would have to change the calipers on the front too.
Thanks

AnswerHi Ken,
You may find websites dedicated to the older KZ's that have other KZ owners who have the fix or a resource for a fix for your MC. Do an internet search.
For custom brakes, check out Performance Machine. I've used their wheels and brakes on my roadrace machines. Very trick, but expensive. Many custom MC fabricators use PM products.
