Fork Rebuild Questions

So, my forks lifted from a stock 05 are showing signs they need to be resealed - the fork scrapers are starting to look pretty crispy, etc. However, got a question - since I am going to be changing the fork seals and scrapers, should I also replace the bronze bushings in the forks or are they like the older TRAC forks where they almost never need those bushings replaced?

Also, I know some people have installed fork gaiters. Anyone reported back with long term durability reports yet? Can't seem to find any in the archives.

Gaiters are cool looking, that's about it. "Modern" seals/scrapers do not need them.
I would replace bushings as well. There is a chance you wont need them but you wouldn't know till you get there. A few bucks and you will be taking it all apart anyway, why not to change them? Buy only OEM parts (seals etc) - best quality.

OEM parts only. replace both bushings, and both seals on each side.

Run +30mm over stock of oil height for better overall spring rate.

Yeah, OEM Honda parts for the fork seals is something I learned long ago. Okay, will order in all four brass/bronze bushings ahead of time as well as the seals and scrapers. I intend to paint the fork lowers black and will probably install black gaiters to work on the 'blacker than the blackest black' look.

The service manual says to inspect and replace if needed. I, however, stick with the idea of "If I'm in it this far, may as well do the rest so I don't have to worry about it."

if you love your motorcycle, set it free.. if it comes back and hits you.. you highsided

why 30? One should install air spring as much as one needs to utilize close to full range of travel without bottoming out. Air spring only goes into effect at the lower end of the stroke.
I would install whatever manual says for that fork, put a zip tie and test ride it while trying to bottom them out. Do 2-3mm adjustments as needed until all is good.
4ml of oil should add about 3mm of height in 43mm forks. A = π X rē
