Did the oil swap on my XCR-LO forks on my Hoodoo a few months ago, easy to do. I followed the instructions on mtbr for the Raidon fork so here’s what I did:
Remove all grease you can.
Soak foam rings in oil.
Check seals are not worn, mine were brand new but yours may be curvy small bits of grit in the grease. If you need new ones the ones for a fox 32 fit. Grease them with a light suspension grease.
Reassemble with 15 ml of fork oil in each leg.
Use plumber’s tape round leg bolts to help with sealing.
Really simple to do and has transformed the fork completely. The only issue I have is if I put the fork upside down for more than half an hour, the oil then starts to seep out past the lockout lever. Other than that it’s been all win!
