Recently found that one of my forks was leaking oil and decided that the seal was probably shot. I have had the bike for 16 years and it's been out in all weathers and never let me down. Had a look on YouTube to see if it was possible to change the seals myself. Watched a few videos and it all looked pretty straight forward so I bought all the relevant bits such as seals, new circlips, bushes, and thicker fork oil. After a little bit of trouble managed to get the forks off and stripped down. Replaced the seals but then found that for a reason that totally alluded me when all the internals are put back inside the spacer protrudes about 4 inches above the top of the stanchion and I cannot put the end cap back on. I followed the instructions on the videos exactly but something is wrong. Any advice would be appreciated. Many thanks.
