June 21, 20251 yr Hi all, Just stripped my forks down on a Montesa 4rt and replaced lower and upper bushes along with new seals and oil. My question is to do with the right fork leg: Do I fit fork cap with fork compressed or extended? Im thinking compressed as that’s when you measure the oil height and it will work better with controlling the spring rebound. I can’t see this info in the manual. Pic of both legs ready to fit with difference in length.
