Oddly enough, on an FZ-1 you can't see diddly with FZ-1 mirrors. Here is something many of us have done on an FZ, you might like it even better with your FZ mirrors on the FJR.
Remove the mirrors and drill the rivet out. Use a vise grip or something to hold the parts together because they are loaded and come flying out when the rivet stops being a rivet.
Swap the left base to the right side and the right base to the left side. This will essential mount them upside down from there normal positioning. Bolt the stalk to the base using the spring washers and a bolt and nut to replace the rivet. Some people have also put a toilet tank washer between the base and mirror stalk. Some have reported that vibration is lessened by doing this. YMMV. I didn't notice any difference.
What this does is extends them out a small amount and lowers the mirrors. Visibility is improved further still and, on an FZ-1, wind turbulence off the mirrors is greatly reduced. I do not know if the same would happen with the FJR aerodynamic package.
I'll probably swap my already modified mirrors from the FZ to the FJR some boring rainy weekend this winter.
