It feels like my front suspension is "loose" as it clunks on landings (some of the time) right on impact. Suspension compression/rebound action appears smooth. I checked the triple clamps - Ok but have not checked stem tightness apart from the locking nut in the top which appears tight. Anyone ? Also when do you know if your fork seals need replacing ? I have used the feeler guage trick a couple of times already to clean it up a little with good results. If I do this and it doesnt work anymore is that a good enough guage ? Other than inspection ?
