You mentioned the fork seals earlier. If possible the Honda seals seem to hold up far better. The mist important thing to do when replacing those seals is polishing the forks.
They need to be carefully examined and polished. Old time wrenches ran their thumbnail over them and if you could feel it it would cause a leak. They advised polishing any imperfection using extra fine sandpaper using ATF as a lubricant. The sandpaper is used like a shoeshine rag. After that polish them with Mothers or another polish.
Very minor imperfections you don;t think will polish out, can be filled with crazy glue which will polish very smooth and hold if you clean the spot properly.
This process is a pain in the ass, but, I have gotten 5 years so far out of OEM Honda seal and this process. The "Never Leaks" lasted 2 years.
