I only know this works for my 1997 FZJ80 40th ann., but it should work for many cruisers. Basically, I drilled a hole through the visor near the mount, put in a small bolt (10mm head and nut) with normal washers and a nylon insert locking nut. I tighten the bolt when it is droopy and loosen it if it gets too tight. It has worked well for 6 years so far. It isn't very noticeable, but when I do notice it, it looks like a couple hundred dollars.
I felt around for the wire to the lighted mirror, couldn't really feel it, took an exacto knife and cut a small X so the drill would not pull a thread and rip up the visor cloth. I drilled the hole about 1 cm down and 1cm over from the corner where the mounting axle (this may not be the real name) comes out of the visor. I drilled at a slow speed (be careful to stop if it looks like the cloth is wrapping around the drill bit) until through all but the other side cloth, and made another small X on the exit side. I inserted a small bolt, 16mm long x 6 x 1.0, and tightened the bejeezus out of it until it finally started to have an effect. It may seem like it won't tighten enough, but it does finally. Then I kept a couple of 10mm wrenches in the console until I had the tightness fine tuned.
You could use those plastic screw or bolt head hiders or paint the bolt or use black chrome bolts or ? if you want it to be hidden or better looking, but so far no one has said anything or seemed to notice.
Good luck, tell me if you need more info or a picture.
