I will need new doggies and maybe a heavier spring for my weight to get the right sag amount I understand it should be between 30-40 mm with me on the bike with all my riding gear on.
Thanks Didier9 for the quick reply and helpful info.
The R6 shock is a little stiffer than the stock FZS1000, so you may be just fine with it (the shock itself is actually quite a bit stiffer, but the new dogbones temper that somewhat, so after the upgrade, the suspension is supposed to be about 15% stiffer)
Apparently, the stock shock on the FZS1000
0 has a tendency to bottom out (due to soft spring and lack of fast/slow compression damping adjustment), so the R6 shock is supposed to help with that. I have not personally experienced it even though I am at least 210 lbs with gear but I do not ride hard.
Someone on the FZ1OA forum said the shock from the S1000RR is even better, but a quick look shows that it is hard to get and quite a bit more expensive (more like >$250) so I did not go that route.
Also suggested was to have the shock rebuilt by Traxxion in the US. That also is upward of $400 (plus shipping both ways, plus no bike for a couple of weeks at best) so that was out of the question for me as well.
For me, I will just be happy if the rear of the bike tracks as well as my daughter's FZ-07's when I am done with it. The FZS1000 fork is fine, as long as you have it serviced regularly.
