Can you give some more details on these mods...this is exactly what I would like to do on my bike...
Got a how to? and where you sourced the parts?
Life being life, I haven't been around in a while. Sorry to take so long to answer...
Source is almost always eBay. As far as a howto, it's relatively simple.
You'll need 2005+ R6R running gear (shocks, top and bottom clamps with steering tube, calipers, rotors and fender), two All Balls Racing bearings (top 99-3540-5, bottom 99-3538), either risers for handlebars, or clip-ons (I would strongly recommend Apex riser clip-ons, 3" or 4" version, 50mm). You can also purchase an R6R front wheel, or use your FZ6 stocker; it's the same wheel.
1. Remove stock FZ6 running gear, all the way to a bare head tube
2. Remove stock bearing races (I used a deadblow and a piece of aluminum pipe to "press" out the races.)
3. Install new All Balls bearing races (again using deadblow and aluminum pipe, being careful to tap them in evenly.)
4. Remove old bottom bearing race from R6R steering tube (methods vary.)
5. Install new All Balls bearing onto R6R steering tube (deadblow and pipe again.)
6. Mount upper and lower triple through the head tube using R6R triple nut and washer
7. Insert R6R fork tubes into clamps
8. Remove FZ6 rotors from wheel (if re-using FZ6 wheel.)
9. Install R6R rotors onto wheel (I purchased new stainless shoulder bolts from amazon.com)
10. Remount wheel, calipers and fenders
11. Figure out a brake line solution
Remember that you don't NEED to buy a new axle, spacers or wheel. These items from the FZ6 will fit the R6R setup. Also optional, though recommended, is the R6R master cylinder (radial.)
Mounting options for naked headlights is almost nil with this setup. I had to have custom brackets made for my FZ1 headlight. I'm running CBR1000RR HeliBars, but they are way too low to be comfortable for much other than my short commute. They look badass though. Also to be considered, mounting your speedo cluster; mine mounts with the FZ1 bracket, others will be a chore. Depending on which bars you choose, you might need to look into custom length clutch/throttle cables. I used the R6R throttle assembly and made my own brass cable ends (modified to use setscrews, from solder-on type) on cables I cut myself.
