Honestly... that is your stand on forks. Better recheck it.
The reason you tear into a fork that is not leaking is... well actually 2 reasons.
1. To prevent from leaking, as stated.
2. To put in new bushings. At which point you have to pull apart forks anyway, and only a moron would use old parts like seals then.
Don't replace the bushings... well that's not so smart. The bushing is what the leg rides against in the fork lower. Once it wears off its brass its done and will start to eat away the fork lower. Not good. That is why you service your forks before they start leaking.
Need more?
Example... here is the fork bushings on my chopper at 6k miles. I only did them cause they were off the bike anyway. But they weren't due till 10k. You can laready see the worn effect on the bushing.
Further, the fork oil was horrible
So then new parts and new oil...
