Fork Oil Service Interval?

[ky busa]

It will change on its own someday

Every year or 10000kms, whichever comes first. Surprising how much the oil degrades and how contaminated it is.

Bob go away,,, 50 thousand miles on an OEM chain

But it was still good, you said so yourself. messy but good

Here’s the best fork servicing vid I’ve ever seen!
Well worth a watch if you’re interested in the technical side of forks…
Enjoy!

the only main difference at the vid is that he wrenches a standard (standing) fork
in opposite to our busa´s usd (hanging) fork

the job itself is more or less at both types the same

opening, disassembling completely, cleaning and reassembling

what I personally have never done yet is to disassemble the valves for tension and compression, because I assume that the fresh oil flushes these valves after only a few km / miles and thus also cleans them.
but
if a fork has not been taken apart for more than 10 years, i think that dismantling the valves into their individual parts is strongly recommended.

and here the dirct link to the video at yt

listen exactely at minute 6:00 what the expert say about how long the oil should stay at max inside
(lill hint . 3-4 years)

and here a pic of a 3.5 year old fork oil (taken in summer ´20 at a ´00 busa)

and i regret that smells can´t be send same way
but if i say "close to sewer" one should understand.

I personally was close to gagging again.
