I will be 60 this Monday the 27th of November. I plan to spend the day upgrading the stock front disc with an R1 1000 caliper, Goodrich braided line FZR600 rotor and R1 master cylinder and reservoir. My dear friend and brilliant mechanical engineer Mark Haase designed and built the adapter bracket depicted and figured out all the spacing and hardware requirements. The swap requires a 12MM spacer between the rotor and wheel hub for rotor clearence which just happens to be the thickness of the stock disc mount which he refers to as a hat.
I have a 74 RD parts bike and he told me to use a cutoff wheel and cut out the part that mounts the hub and make it round for use as a spacer or have one machined. The conversion also requires 6 M8 x 1.25 x 40MM bolts to attach the FZR rotor. 
The caliper will mount in the stock location on the RH fork lower which translates to using a LH R1 caliper which is normally mounted behind the forks. The stock brakes are adequate but require considerable lever pressure even with new components and steel braided lines. I am spoiled by the 2 fingers stopping ability the R1 conversion on my RZ gave me...More pictures will follow as the work progresses. I sourced all the parts off of ebay for less than $150.
