Garth,
I took my K4 forks off yesterday and, looking at the volume of rust in the circlip area, I can't imagine my circlips will be reusable. Were you ever able to score replacements? I'm going to put off replacing my fork seals until I can be sure I can clip them back in.
Fore reference, I'm needing:
SKU: 94521-48000
CIRCLIP (INNER) (48MM) (Honda Code 0255349) (NOT AVAILABLE)
